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.
