This book was released on 1971 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: Weighting of variables in a regression equation so as to maximize prediction of a criterion presents several problems. Optimal weighting in the sample case means that chance-related error is also weighted indiscriminately. Because such error will not relate to the criterion in subsequent samples, a sample multiple correlation (R) will be on the average larger than the population value (overfit), and its value on cross-validation will be lower than in the quation-development sample (shrinkage). The influence of characteristics of the population and other conditions of the sampling situation on the outcome and stability of the regression equation has not been well understood. In particular, the role played by the relationship of initial predictor set size (M) to sample size (N) has not received adequate attention. The report attempted to examine and isolate the role of sampling error in the magnitude and stability of sample multiple R values obtained by incremental test selection techniques. The effect of selected factors on the impact of sampling error was examined. Three proposed shrinkage estimation formulas were evaluated for effectiveness, and a search was conducted for more efficient formulas incorporating the M/N ratio. Method of controlling shrinkage and overfit were discussed and evaluated. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Contributions to Correlational Analysis provides information pertinent to the fundamental aspects of correlational analysis that can be used to replace and enhance many of the parametric and nonparametric inferential statistical tests. This book discusses the basic concern of correctional analysis, which is the relationship between two sets of measure. Organized into 18 chapters, this book begins with an overview of the nature of correction analysis. This text then explains the simple linear relationships in which explains the simple linear relationships in which Y and X each consists of some single measurement per person and the relationship is assumed to be linear. Other chapters consider basic ways of expanding the process to include more or different measurements of either X or Y but with no attempt to find the best functions. This book discusses as well the topic of factor analysis. The final chapter deals with canonical correlation. This book is a valuable resource for psychologists.

Download or read book Regression Modeling Strategies written by Frank E. Harrell and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 583 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many texts are excellent sources of knowledge about individual statistical tools, but the art of data analysis is about choosing and using multiple tools. Instead of presenting isolated techniques, this text emphasizes problem solving strategies that address the many issues arising when developing multivariable models using real data and not standard textbook examples. It includes imputation methods for dealing with missing data effectively, methods for dealing with nonlinear relationships and for making the estimation of transformations a formal part of the modeling process, methods for dealing with "too many variables to analyze and not enough observations," and powerful model validation techniques based on the bootstrap. This text realistically deals with model uncertainty and its effects on inference to achieve "safe data mining".
