ASIN: 0471255114 |
Book Description
A modern and highly innovative guide to industrial experimental designThe past two decades have seen major progress in the use of statistically designed experiments for product and process improvement. In this new work, Jeff Wu and Michael Hamada, two highly recognized researchers in the field, introduce some of the newest discoveries in the design and analysis of experiments as well as their applications to system optimization, robustness, and treatment comparisons in the diverse fields of engineering, technology, agriculture, biology, and medicine.
Drawing on examples from their impressive roster of industrial clients (including GM, Ford, AT&T, Lucent Technologies, and Chrysler), Wu and Hamada modernize accepted methodologies, while presenting many cutting-edge topics for the first time in a single, easily accessible source. These include robust parameter design, reliability improvement, analysis of nonnormal data, analysis of experiments with complex aliasing, multilevel designs, minimum aberration designs, and orthogonal arrays. Other features include:

A Superb Graduate Textbook.......2002-10-02
Wu and Hamada (2000) is a superb textbook in this regard. The book is loaded with a number of most important modern topics in design of experiments, including robust parameter design, minimum aberration, designs with complex aliasing, and generalized linear models (p. xvii). These modern topics only receive some courteous treatment, if any at all, in most of design textbooks. The importance of these topics cannot be over-stated. It is impossible for an instructor to provide a detailed coverage of all the important topics in any design course. Practical problems often require the use of certain methods, which may or may not be touched in a design course. Therefore, we will often have to go back to our graduate textbooks to do some further reading. The comprehensive design tables in Wu and Hamada (2000)
also make this further learning process easier. For those who are doing research in the area after their graduate studies, Wu and Hamada (2000) is a necessity. Accessing design literature through journals is much more inconvenient and time-consuming. Wu and Hamada (2000) is also a suitable textbook for a design course for undergraduates majoring in statistics, or other areas of mathematical sciences.
If I can only own one design book, this is the one.
Not in touch with Grad Students..........2002-01-19
Use of the 'et cetera' function, or a failure to work out examples. I'm not sure if I'm in a minority with this opinion, but I believe, after many years as a graduate student that examples should be worked on in their entirety. Unfortunately, this in not the case with this textbook. There are numerous places in this text where the authors reference, with great generality, pervious half-worked examples or formulas. Not only does this make the text sometimes difficult to follow, it also reduces the usefulness of the book as a self teaching tool.
The text also fails to include even some of the solutions to its exercises. I'm not sure why many authors fail to include even some of the solutions to their chapter exercises. In my opinion, I believe that this is a serious weakness in text. Most professors who teach graduate level courses create their own problem sets. By failing to include even partial solution sets, the authors minimizes or completely destroys any benefit of including exercises in the text (especially if you are not reading this text as part of a course). There is no benefit of working out exercises if you can not correct or even identify your mistakes.
If I had to have just one "Design of Experiments" book, I would not choose this one. Although there are many great things about this book, it is notoriously light on Split-Plot experiments. In fact, Split-plot experiments (which are very common) only receive a cursory mention. If you are looking for Books on Designs of experiments, I suggest you look at "Design and Analysis of Experiments" by Douglas Montgomery, or maybe even the older "Statistical Design and Analysis of Experiments" by Mason, Gunst, and Hess.
authoritative and thorough treatment.......2000-09-19
The book is intended for scientists and engineers as well as statisticians. The authors deliberately introduce the concepts gently, starting with a real problem and constructing and analyzing a design type considered in the chapter. This is done consistently from chapters 3-13.
They start with the simplest ideas and designs and build up. Chapter 1 deals with single factor experiments and Chapter 2 with experiments with more than one factor, starting with two. Section 1.1 provides an historical perspective which I find valuable. It leads to a classification of design problems that are distinct and they show how they arose in very different contexts. They do a good job of setting the stage for the remaining chapters. The categories are (1)Treatment Comparisons (the traditional agricultural experiment), (2) Variable Screening, (3) Response Surface Exploration, (4) System Optimization and (5) System Robustness. Although the theory of optimal designs is not covered in detail, the role of optimal designs is mentioned as is the early work of Kiefer (section 4.4.2)and reference to the recent book by Pukelsheim is given.
In Chapter 4 on fractional factorial experiments at two levels, concepts of resolution and aberration are clearly explained. I think it helps that the authors make these concepts concrete through the illustrative examples. I have often looked at standard design texts and found myself confused about the distinction between resolution III, IV and V designs.
There are several features that set this book apart from other books on design of experiments. Some attention is given to the one-factor-at-a-time approach. Most books ignore this commonly used approach and its many drawbacks. The authors explain its four main disadvantages and illustrate the problem with a design example. In my experience in industry, many engineers are not trained well in statistics and although it may seem clear to statisticians that one-at-a-time approaches overlook interactions or dependencies between variables, the engineers often do not. They see this approach as a way to simplify their search for the best operating conditions. I published an article in the mathematical modeling literature that also was intended to demonstrate the value of statistical design methods over the one-at-a-time approach. Latin square and Graeco-Latin Squares are covered as well as the more common factorial and fractional factorial designs. They also cover randomized blocks and balanced incomplete blocks. The concept of pairing (blocking) is well illustrated with a particular analysis of variance done both with and without pairing. Underlying assumptions are brought out and never hidden. The principles that are the basis for selection of fractional factorial designs are made explcit. Practical nonregular designs including the popular Plackett-Burman designs are well covered. Chapter 10 provides the basis and motivation for robust parameter designs. It also includes a discussion of the signal-to-noise ratio approach of Taguchi and describes some of its weaknesses. Chapter 11 looks at various performance measures for robust parameter design and compares several designs with respect to these parameters.
In the early chapters, the analysis of variance is presented clearly with all the required assumptions. Multiple comparison methods are discussed. Good references, both recent and old, are provided on each topic. My only disappointment was the omission of the recent resampling approaches to p-value adjustment due primarily to Westfall and Young.
Another interesting and unique aspect of the book is the presentation of Bayesian variable selection strategies. This introduces much of the interesting new work in Bayesian methods using the Markov Chain Monte Carlo methods.
Chapters 12 and 13 cover topics you will not find in other experimental design books. Chapter 12 deals with experiments to improve reliability and 13 with nonnormal data. Use of generalized linear models and transformation of variables is well covered in the book.
This book is a worthy sequel to Box, Hunter and Hunter. It is a great introductory book for experimental design courses and a great reference source for scientists, engineers and statisticians. It is already gaining in popularity.
A classic book on experimental design.......2000-09-02
This book devotes more than half of its chapters to cover the rapid new developement in past two decades that was not ready to be coverd by BHH back in 1978.
First four chapters cover the same classic designs in BHH. Chapter 5 discusses in detail on three level factorial designs which is very useful but was not covered by BHH. Chapter 6 lists useful mixed level designs. Chapters 7 and 8 explain design and analysis of Platt-Burman and other irregular designs. Chapter 9 is on response surface design. Chapters 10 and 11 are devoted to Robust designs, better known as Taguchi method. Chapter 12 is specific on reliability study using experimental design. Chapter 13 wraps up the book with a nice discussion on how to deal with non-normal responses in an experiment.
The book is full of data from real experiments. There are on average 7-8 in each chapter. For practioners, there are hundreds of designs tabled after each chapter.
The authors explain the strategy of designing experiments and doing data analysis very clearly through examples. There are also pletty of exercise problems after each chapter. It could be used as a textbook for two semester experimental design courses.
The authors did not try to cover everything but rather stay focused. For example, optimal designs are left out from the book. Most of the data analysis method in the book requires to be done using statistics softwares but you couldn't find a single computer command in the book. Maybe in the future, we will have SAS books, S+ books, and Minitab books to go along with this book. At this moment, the software developers have to catch on.

A must read for any architect........2003-03-17
An economic revolution using mud.......2002-04-10
Sometimes a book is so ahead of its time it can sink beneath the waves before it's appreciated. Such a book was 'Architecture for the Poor', written in 1969 and originally published by the Ministry of Culture in Cairo. Written with the help of a fellowship from the Adlai Stevenson Institute of International Affairs it was published in America by the University of Chicago in 1973 and in a second impression in 1976. But even then it was only taken up by the fringes of the solar energy movement as a neat idea for a different culture and climate. Currently its out of print. The author died in 1989 having received some praise in his home country of Egypt but having seen no actions to take up his ideas for helping peasants take control of their lives by taking charge of the creation of their homes and communities.
Dr Fathy was officially an architect but his talents as an amateur anthropologist, sociologist, psychologist, inventor, and economist are what make him great. His holistic approach to solving the housing problems of a poverty level community (and his vision to see how they could be applied to a whole country) takes in the gamut from reviving the craft of mud brick making (along with the traditional masonry building of vaults and domes to roof simple mud structures) through to solving the problems of parasitic worm infections that debilitate entire populations infected through their water supply systems. Every aspect of village life receives his attention: how to adapt an Austrian heating system to make a cooking stove more efficient, how to share a house with cows more hygienically, where to do laundry, how to build a better school, how to provide an alternative income from tomb robbing for the peasants, and how to tactfully delouse peasants using the luxury of a Turkish bathhouse rather than the chilly chemicals of a government mandated cold shower.
His appreciation that some inefficiencies are functional within a society makes the changes he does make even more impressive. Fetching water from the village pump in water jars is one of the few occasions a girl has to be seen out in public in Moslem society. Providing running water to every house would derail the marriage process within that society. However he is happy to create plumbing inside the home ? running pipes to the kitchen from rooftop storage jars across the middle of rooms, so if they leak the occupants will have to fix them not ignore the drips until the wall is eroded. Fathy's changes are not just improvements to make a peasants life more like a modern westerners life ? that is impossible given the astonishingly low income of these people. They are changes that make life easier or healthier while striving to maintain traditions and strengthen society because they understand what is behind the tradition. For example splitting the village up into single home farmsteads would expose the individual families to roaming bands of thieves, so it's necessary to let houses huddle together for protection and for cows ? more valuable than children ? to stay inside the house.
Yet this book is not just about practicalities of house or village building ? it's also about the need for beauty in the life of even the poorest amongst us. Dr Fahey's desire to restore an appreciation for craftsmanship to all members of society especially by restoring the ability of the poor to control the creation of their own homes is inspiring. An architect can help the process along only if he or she can learn to see life outside the urban world of modern design. This book shows how an architect with an academic education can be of some help to a peasant faced with grinding poverty but only if equipped with the ability to move to the world of that peasant and see how alien western technological solutions can be.
Fahey's ideas are not just applicable to Egyptian society, reading this book made me aware of the similarities of problems faced by peoples in many middle eastern countries, particularly Afghanistan which is trying to rebuild itself and could use Dr Fahey's techniques to rehouse its population cheaply and empoweringly. It's even possible to extend his ideas to other hot dry climates such as Southern California, and the desert states of the US, to Mediterranean countries and to many parts of Africa, South America, and Australia. Wherever issues of building cost or those of insulation, shelter and energy efficiency in a hot dry climate need addressing Dr Fahey's solutions should be considered. This book needs to be reprinted; clamor for copies and see if we can make it the bestseller it should have been the first time around.

My favorite Science resource by far.......2001-09-10
Sorted by category (which not all resource books are!) this book is easy to use, has ample instruciton for the teacher and more than plenty activities/experiments to choose from.
Whether you pick and choose from throughout the book in a hodge-podge sort of way, or you use the book straight through with "science themes" this book will provide you more ideas than you can use. One of the very few science books for this age group that I've seen that provides reproducibles for many of the acitivities.

Learning More From Social Experiments: Evolving Analytic Approaches
Manufacturer: Russell Sage Foundation Publications ProductGroup: Book Binding: Hardcover Similar Items:
ASIN: 0871541270 |
Book Description
Policy analysis has grown increasingly reliant on the random assignment experimenta research method whereby participants are sorted by chance into either a program group that is subject to a government policy or program, or a control group that is not. Because the groups are randomly selected, they do not differ from one another systematically. Therefore any differences between the groups at the end of the study can be attributed solely to the influence of the program or policy. But there are many questions that randomized experiments have not been able to address. What component of a social policy made it successful? Did a given program fail because it was designed poorly or because it suffered from low participation rates? In "Learning More from Social Experiments," editor Howard Bloom and a team of innovative social researchers profile advancements in the scientific underpinnings of social policy research that can improve randomized experimental studies.Using evaluations of actual social programs as examples, "Learning More from Social Experiments" makes the case that many of the limitations of random assignment studies can be overcome by combining data from these studies with statistical methods from other research designs. Carolyn Hill, James Riccio, and Bloom profile a new statistical model that allows researchers to pool data from multiple randomized-experiments in order to determine what characteristics of a program made it successful. Lisa Gennetian, Pamela Morris, Johannes Bos, and Bloom discuss how a statistical estimation procedure can be used with experimental data to single out the effects of a program's intermediate outcomes (e.g., how closely patients in a drug study adhere to the prescribed dosage) on its ultimate outcomes (the health effects of the drug). Sometimes, a social policy has its true effect on communities and not individuals, such as in neighborhood watch programs or public health initiatives. In these cases, researchers must randomly assign treatment to groups or clusters of individuals, but this technique raises different issues than do experiments that randomly assign individuals. Bloom evaluates the properties of cluster randomization, its relevance to different kinds of social programs, and the complications that arise from its use. He pays particular attention to the way in which the movement of individuals into and out of clusters over time complicates the design, execution, and interpretation of a study.
"Learning More from Social Experiments" represents a substantial leap forward in the analysis of social policies. By supplementing theory with applied research examples, this important new book makes the case for enhancing the scope and relevance of social research by combining randomized experiments with non-experimental statistical methods, and it serves as a useful guide for researchers who wish to do so.

Architecture and Landscape: The Design Experiment of the Great European Gardens and Landscapes (Architecture & Design)
Clemens Steenbergen , Wouter Reh , and Gerrit Smienk Manufacturer: Prestel ProductGroup: Book Binding: Paperback Similar Items:
ASIN: 3791317202 |
Book Description
The great parks and gardens of Europe come alive by the skilful interplay of natural landscape and architectural elements. Throughout the ages, this relationship has been treated in different ways. The gardens of the Italian renaissance in the 15th or 16th century were based on rational plans, whereas the French parks of the Baroque period seem more geometric in design, and the English parklands of the 18th century present a scenic composition. In this publication historical gardens from all over Europe are graphically analysed. By highlighting the design processes, these analyses also function as models for future landscape projects. More than 30 renowned gardens have been documented with a wealth of illustrations. Amongst the parks presented are Palladio's Villa Emo, the perfect order of the Baroque garden Vaux-le-Vicomte near Paris or the pastoral yet mysterious park of Blenheim Palace near Oxford. Clemens Steenbergen and Wouter Reh are landscape architects and Professors at the University of Delft.Books:
