Interpreting Regression Effects Custom Dialog: An SPSS Plug-in to the R Yhat Package

Abstract

This paper presents an SPSS custom dialog (Interpreting Regression Effects) that was developed to access R software that helps researchers more fully understand how sets of predictor variables contribute to a regression model. The Interpreting Regression Effects custom dialog allows researchers to consider a wide variety of predictor and all-possible subset related metrics when interpreting regression effects including regression weights, validity coefficients, structure coefficients, product measures, relative important weights, all-possible-subsets regression, commonality coefficients, and dominance weights.
