Statistics : a very short introduction by
D. J Hand(
)
31 editions published between 1987 and 2015 in 4 languages and held by 2,479 WorldCat member libraries worldwide
From the Publisher: Statistical ideas and methods underlie just about every aspect of modern life. From randomized clinical trials in medical research, to statistical models of risk in banking and hedge fund industries, to the statistical tools used to probe vast astronomical databases, the field of statistics has become centrally important to how we understand our world. But the discipline underlying all these is not the dull statistics of the popular imagination. Long gone are the days of manual arithmetic manipulation. Nowadays statistics is a dynamic discipline, revolutionized by the computer, which uses advanced software tools to probe numerical data, seeking structures, patterns, and relationships. This Very Short Introduction sets the study of statistics in context, describing its history and giving examples of its impact, summarizes methods of gathering and evaluating data, and explains the role played by the science of chance, of probability, in statistical methods. The book also explores deep philosophical issues of inductionhow we use statistics to discern the true nature of reality from the limited observations we necessarily must make

The improbability principle : why coincidences, miracles, and rare events happen every day by
D. J Hand(
Book
)
13 editions published between 2014 and 2015 in English and Undetermined and held by 1,355 WorldCat member libraries worldwide
"An eyeopening and engrossing look at rare moments, why they occur, and how they shape our world In The Improbability Principle, the renowned statistician David J. Hand unveils his groundbreaking argument that extraordinarily rare events are in fact commonplace. Weaving together fascinating new ways to think about chance, Hand highlights his "law of near enough," the "look elsewhere effect," and more, doing for probability what Newton's laws of motion did for mechanics. Through humorous and engaging tales of twotime lottery winners, gambling gone wrong, and bizarre coincidences that we can't quite fathom, Hand argues that extremely unlikely events must happen, and no mystical or supernatural explanation is necessary to understand why. Hand's investigation, grounded in statistics and brought to life with fascinating anecdotes, finally explains "unexplainable" events such as unexpectedly bumping into a friend in a foreign country and coming across an unfamiliar word twice in one day. Along the way, we learn what the Bible and Shakespeare have in common, just how to win the lottery, why financial crashes are par for the course, and why lightning does strike the same place (and the same person) more than once. As Hand makes clear, we can rest assured that we'll experience a "miracle" roughly once per month. An irresistible adventure into the laws behind chance moments, The Improbability Principle transforms how we think about business decisions, everyday encounters, serendipity, and luck"

The wellbeing of nations : meaning, motive and measurement by
Paul Allin(
)
14 editions published in 2014 in English and held by 818 WorldCat member libraries worldwide
"What is national wellbeing and what is progress? Why measure these definitions? Why are measures beyond economic performance needed and how will they be used? How do we measure national wellbeing & turn the definitions into observable quantities? Where are we now and where to next? These questions are asked and answered in this much needed, timely book. The Wellbeing of Nations provides an accessible and comprehensive overview of the measurement of national wellbeing, examining whether national wellbeing is more than the sum of the wellbeing of everyone in the country, and identifying and reviewing requirements for new measures. It begins with definitions, describes how to operationalize those definitions, and takes a critical look at the uses to which such measures are to be put. The authors examine initiatives from around the world, using the UK 'measuring national wellbeing programme' as a case study throughout the book, along with case studies drawn from other countries, as well as discussion of the position in some countries not yet drawn into the national wellbeing scene"

Intelligent data analysis : an introduction by
M Berthold(
Book
)
49 editions published between 1999 and 2011 in English and held by 772 WorldCat member libraries worldwide
"This monograph is a detailed introductory presentation of the key classes of intelligent data analysis methods. The twelve coherently written chapters by leading experts provide complete coverage of the core issues. The first half of the book is devoted to the discussion of classical statistical issues, ranging from the basic concepts of probability, through general notions of inference, to advanced multivariate and time series methods, as well as a detailed discussion of the increasingly important Bayesian approaches and Support Vector Machines. The following chapters then concentrate on the area of machine learning and artificial intelligence and provide introductions into the topics of rule induction methods, neural networks, fuzzy logic, and stochastic search methods. The book concludes with a chapter on Visualization and a higherlevel overview of the IDA processes, which illustrates the breadth of application of the presented ideas"Back cover

Finite mixture distributions by
Brian Everitt(
Book
)
15 editions published in 1981 in English and Undetermined and held by 552 WorldCat member libraries worldwide
Finite mixture distributions arise in a variety of applications ranging from the length distribution of fish to the content of DNA in the nuclei of liver cells. The literature surrounding them is large and goes back to the end of the last century when Karl Pearson published his wellknown paper on estimating the five parameters in a mixture of two normal distributions. In this text we attempt to review this literature and in addition indicate the practical details of fitting such distributions to sample data. Our hope is that the monograph will be useful to statisticians interested in mixture distributions and to reƯ search workers in other areas applying such distributions to their data. We would like to express our gratitude to Mrs Bertha Lakey for typing the manuscript. Institute oj Psychiatry B.S. Everitt University of London D. l Hand 1980 CHAPTER I General introduction 1. 1 Introduction This monograph is concerned with statistical distributions which can be expressed as superpositions of (usually simpler) component distributions. Such superpositions are termed mixture distributions or compound distributions. For example, the distribution of height in a population of children might be expressed as follows: h(height) = fg(height: age)f(age)d age (1. 1) where g(height: age) is the conditional distribution of height on age, and/(age) is the age distribution of the children in the population

A handbook of small data sets by
D. J Hand(
Book
)
29 editions published between 1993 and 1996 in English and Undetermined and held by 485 WorldCat member libraries worldwide
"Teachers of statistical methodology frequently fabricate data sets to illustrate techniques or phenomena or for use in examination questions. This is not ideal, as artificial data sets can hinde from the student the relevance and importance of statistics in the modern world. This book offers teachers more than 500 real small data sets, each of which is accompanied by a description of the reallife problem leading to it. The book thus provides a unique collection of actual scenarios and data that can be used to illustrate statistical techniques, enabling teachers to provide convincing worked example and set realistic exercises."Publisher's description

Dark data : why what you don't know matters by
D. J Hand(
)
12 editions published between 2019 and 2020 in English and Italian and held by 349 WorldCat member libraries worldwide
"Data describe and represent the world. However, no matter how big they may be, data sets don't  indeed cannot  capture everything. Data are measurements  and, as such, they represent only what has been measured. They don't necessarily capture all the information that is relevant to the questions we may want to ask. If we do not take into account what may be missing/unknown in the data we have, we may find ourselves unwittingly asking questions that our data cannot actually address, come to mistaken conclusions, and make disastrous decisions. In this book, David Hand looks at the ubiquitous phenomenon of "missing data." He calls this "dark data" (making a comparison to "dark matter"  i.e., matter in the universe that we know is there, but which is invisible to direct measurement). He reveals how we can detect when data is missing, the types of settings in which missing data are likely to be found, and what to do about it. It can arise for many reasons, which themselves may not be obvious  for example, asymmetric information in wars; time delays in financial trading; dropouts in clinical trials; deliberate selection to enhance apparent performance in hospitals, policing, and schools; etc. What becomes clear is that measuring and collecting more and more data (big data) will not necessarily lead us to better understanding or to better decisions. We need to be vigilant to what is missing or unknown in our data, so that we can try to control for it. How do we do that? We can be alert to the causes of dark data, design better datacollection strategies that sidestep some of these causes  and, we can ask better questions of our data, which will lead us to deeper insights and better decisions"
