Abstract:

A lower bound on the noncentrality parameter of the chi-square test of goodness of fit is derived. The bound is a function of the average of absolute discrepancies between theoretical and true probabilities. This bound provides a method that estimates the correspondence between theory and data, and that nullifies, in part, Grants strictures against traditional goodness-of-fit tests. The method also serves as a guide to planning an empirical evaluation of a quantitative theoretical model, when a chi-square test of goodness of fit is contemplated. Author
