Optimal Data Analysis

Optimal Data Analysis

Welcome to the Web site for Optimal Data Analysis: A Guidebook With Software for Windows.

Optimal Data Analysis offers the only statistical analysis paradigm that maximizes (weighted) predictive accuracy. This unique book fully explains this paradigm and includes simple-to-use software that empowers a universe of associated analyses. For any specific sample and exploratory or confirmatory hypothesis, optimal data analysis (ODA) identifies the statistical model that yields maximum predictive accuracy, assesses the exact Type I error rate, and evaluates potential cross-generalizability. No other software can accomplish analyses possible via ODA. The book contains numerous examples that simply could not be solved by any statistical method except for ODA.

This Web site will supplement Optimal Data Analysis: A Guidebook With Software for Windows and help keep it current.
