The devil rides again: Correlation as an index of fit

The devil rides again: Correlation as an index of fit Shows that correlations between theoretical predictions and data can be higher for incorrect than for correct models by analyses of 2 sets of hypothetical data. This fact raises questions about the conclusions of recent studies that use correlation as an index of fit. It is proposed that functional measurement provides a sounder basis for model evaluation by placing scaling in the context of model fitting and by testing deviations from prediction rather than concentrating on overall goodness of fit. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Psychological Bulletin American Psychological Association

Abstract

Shows that correlations between theoretical predictions and data can be higher for incorrect than for correct models by analyses of 2 sets of hypothetical data. This fact raises questions about the conclusions of recent studies that use correlation as an index of fit. It is proposed that functional measurement provides a sounder basis for model evaluation by placing scaling in the context of model fitting and by testing deviations from prediction rather than concentrating on overall goodness of fit.
