Data Science and Classification provides new methodological developments in data analysis and classification. The broad and comprehensive coverage includes the measurement of similarity and dissimilarity, methods for classification and clustering, network and graph analyses, analysis of symbolic data, and web mining. Beyond structural and theoretical results, the book offers application advice for a variety of problems, in medicine, microarray analysis, social network structures, and music.

“Brilliant, funny . . . the best math teacher you never had.”—San Francisco Chronicle Once considered tedious, the field of statistics is rapidly evolving into a discipline Hal Varian, chief economist at Google, has actually called “sexy.” From batting averages and political polls to game shows and medical research, the real-world application of statistics continues to grow by leaps and bounds. How can we catch schools that cheat on standardized tests? How does Netflix know which movies you’ll like? What is causing the rising incidence of autism? As best-selling author Charles Wheelan shows us in Naked Statistics, the right data and a few well-chosen statistical tools can help us answer these questions and more.

For those who slept through Stats 101, this book is a lifesaver. Wheelan strips away the arcane and technical details and focuses on the underlying intuition that drives statistical analysis. He clarifies key concepts such as inference, correlation, and regression analysis, reveals how biased or careless parties can manipulate or misrepresent data, and shows us how brilliant and creative researchers are exploiting the valuable data from natural experiments to tackle thorny questions.

And in Wheelan’s trademark style, there’s not a dull page in sight. You’ll encounter clever Schlitz Beer marketers leveraging basic probability, an International Sausage Festival illuminating the tenets of the central limit theorem, and a head-scratching choice from the famous game show Let’s Make a Deal—and you’ll come away with insights each time. With the wit, accessibility, and sheer fun that turned Naked Economics into a bestseller, Wheelan defies the odds yet again by bringing another essential, formerly unglamorous discipline to life.

This volume presents 45 articles dealing with theoretical aspects, methodo logical advances and practical applications in domains relating to classifica tion and clustering, statistical and computational data analysis, conceptual or terminological approaches for information systems, and knowledge struc tures for databases. These articles were selected from about 140 papers presented at the 19th Annual Conference of the Gesellschaft fur Klassifika tion, the German Classification Society. The conference was hosted by W. Polasek at the Institute of Statistics and Econometry of the University of 1 Basel (Switzerland) March 8-10, 1995 . The papers are grouped as follows, where the number in parentheses is the number of papers in the chapter. 1. Classification and clustering (8) 2. Uncertainty and fuzziness (5) 3. Methods of data analysis and applications (7) 4. Statistical models and methods (4) 5. Bayesian learning (5) 6. Conceptual classification, knowledge ordering and information systems (12) 7. Linguistics and dialectometry (4). These chapters are interrelated in many respects. The reader may recogni ze, for example, the analogies and distinctions existing among classification principles developed in such different domains as statistics and information sciences, the benefit to be gained by the comparison of conceptual and ma thematical approaches for structuring data and knowledge, and, finally, the wealth of practical applications described in many of the papers. For convenience of the reader, the content of this volume is briefly reviewed.
With four simple truths as his framework, Charles Murray, the bestselling coauthor of The Bell Curve, sweeps away the hypocrisy, wishful thinking, and upside-down priorities that grip America’s educational establishment.

Ability varies. Children differ in their ability to learn academic material. Doing our best for every child requires, above all else, that we embrace that simplest of truths. America’s educational system does its best to ignore it.

Half of the children are below average. Many children cannot learn more than rudimentary reading and math. Real Education reviews what we know about the limits of what schools can do and the results of four decades of policies that require schools to divert huge resources to unattainable goals.

Too many people are going to college. Almost everyone should get training beyond high school, but the number of students who want, need, or can profit from four years of residential education at the college level is a fraction of the number of young people who are struggling to get a degree. We have set up a standard known as the BA, stripped it of its traditional content, and made it an artificial job qualification. Then we stigmatize everyone who doesn’t get one. For most of America’s young people, today’s college system is a punishing anachronism.

America’s future depends on how we educate the academically gifted. An elite already runs the country, whether we like it or not. Since everything we watch, hear, and read is produced by that elite, and since every business and government department is run by that elite, it is time to start thinking about the kind of education needed by the young people who will run the country. The task is not to give them more advanced technical training, but to give them an education that will make them into wiser adults; not to pamper them, but to hold their feet to the fire.

The good news is that change is not only possible but already happening. Real Education describes the technological and economic trends that are creating options for parents who want the right education for their children, teachers who want to be free to teach again, and young people who want to find something they love doing and learn how to do it well. These are the people for whom Real Education was written. It is they, not the politicians or the educational establishment, who will bring American schools back to reality.

Twenty-four years ago, Charles Murray’s Losing Ground changed the way the nation thought about welfare. Real Education is about to do the same thing for America’s schools.

“The nation needs to be confronted with the crime that we’re committing and the promises we are betraying. This is a book about betrayal of the young, who have no power to defend themselves. It is not intended to make readers comfortable.”

Over the past several years, Jonathan Kozol has visited nearly 60 public schools. Virtually everywhere, he finds that conditions have grown worse for inner-city children in the 15 years since federal courts began dismantling the landmark ruling in Brown v. Board of Education. First, a state of nearly absolute apartheid now prevails in thousands of our schools. The segregation of black children has reverted to a level that the nation has not seen since 1968. Few of the students in these schools know white children any longer. Second, a protomilitary form of discipline has now emerged, modeled on stick-and-carrot methods of behavioral control traditionally used in prisons but targeted exclusively at black and Hispanic children. And third, as high-stakes testing takes on pathological and punitive dimensions, liberal education in our inner-city schools has been increasingly replaced by culturally barren and robotic methods of instruction that would be rejected out of hand by schools that serve the mainstream of society.

Filled with the passionate voices of children and their teachers and some of the most revered and trusted leaders in the black community, The Shame of the Nation is a triumph of firsthand reporting that pays tribute to those undefeated educators who persist against the odds, but directly challenges the chilling practices now being forced upon our urban systems by the Bush administration. In their place, Kozol offers a humane, dramatic challenge to our nation to fulfill at last the promise made some 50 years ago to all our youngest citizens.


From The Shame of the Nation

“I went to Washington to challenge the soft bigotry of low expectations,” the president said in his campaign for reelection in September 2004. “It’s working. It’s making a difference.” It is one of those deadly lies, which, by sheer repetition, is at length accepted by large numbers of Americans as, perhaps, a rough approximation of the truth. But it is not the truth, and it is not an innocent misstatement of the facts. It is a devious appeasement of the heartache of the parents of the poor and, if it is not forcefully resisted and denounced, it is going to lead our nation even further in a perilous direction.
