Effect Size for Anova Designs lays out the computational methods for 'd' with a variety of designs including factorial ANOVA, ANCOVA and repeated measures ANOVA; 'd' divides the observed effect by the standard deviation of the dependent variable.

John Fox introduces readers to the techniques of kernel estimation, additive nonparametric regression, and the ways nonparametric regression can be employed to select transformations of the data preceding a linear least-squares fit.

Sooner or later anyone who does statistical analysis runs into problems with missing data in which information for some variables is missing for some cases. Why is this a problem? Because most statistical methods presume that every case has information on all the variables to be included in the analysis. Using numerous examples and practical tips, this book offers a nontechnical explanation of the standard methods for missing data (such as listwise or casewise deletion) as well as two newer (and, better) methods, maximum likelihood and multiple imputation. Anyone who has been relying on...

All kinds of human behavior are observed, written about, or documented. Ethnographers can be seen as "documentary accountants" -- they observe and provide analysis. This book shows how to use documentary works as data sources and how qualitative and quantitative analysis techniques can be combined. It shows how care must be taken with sampling and coding and gives attention to reliability and validity issues, showing how to begin statistical exploration once the data are assembled.

This book covers the essential information needed to understand the problems involved in translating existing questionnaires and other paper and pencil instruments from one language to another as well as to apply methods for dealing with them. It shows researchers how to identify the problems (comparison of parameters, nomological nets, and semantic problems) with an existing instrument; how to solve each of these problems with step-by-step guidelines; and techniques for reconstructing an instrument or designing an original one to use with different cultural groups. This book will provide...

Do you have data that is not normally distributed and don't know how to analyze it using generalized linear models (GLM)? Beginning with a discussion of fundamental statistical modeling concepts in a multiple regression framework, the authors extend these concepts to GLM (including Poisson regression. logistic regression, and proportional hazards models) and demonstrate the similarity of various regression models to GLM. Each procedure is illustrated using real life data sets, and the computer instructions and results will be presented for each example. Throughout the book, there is an...

This book builds on John Fox's previous volume in the QASS Series, Non Parametric Simple Regression. In this book, the reader learns how to estimate and plot smooth functions when there are multiple independent variables.

Oriented toward the applied researcher with a basic background in multiple regression and logistic regression, this book shows readers the general strategies for testing interactions in logistic regression as well as providing the tools to interpret and understand the meaning of coefficients in equations with product terms. Using completely worked-out examples, the author focuses on the interpretation of the coefficients of interactive logistic models for a wide range of scenarios encountered in the research literature. In addition, the author avoids complex formulas in favor of simple...

The focus in this Second Edition is on logistic regression models for individual level (but aggregate or grouped) data. Multiple cases for each possible combination of values of the predictors are considered in detail and examples using SAS and SPSS are included. New to this edition: * more detailed consideration of grouped as opposed to casewise data throughout the book * updated discussion of the properties and appropriate use of goodness of fit measures, R2 analogues, and indices of predictive efficiency * discussion of the misuse of odds ratios to represent risk ratios, and of...

Covering the basics of the cohort approach to studying aging, social, and cultural change, this volume also critiques several commonly used (but flawed) methods of cohort analysis, and illustrates appropriate methods with analyses of personal happiness and attitudes toward premarital and extramarital sexual relations. Finally, the book describes the major sources of suitable data for cohort studies and gives the criteria for appropriate data. The Second Edition features: a chapter on the analysis of survey data, which includes a discussion of the problems posed by question order effects when...
