IV. Comparison of Cross-Validation with Statistical Inference of Betas and Multiple R From a Single Sample

inference can be developed along two different lines of emphasis. The first of these is concerned largely with the problem of correction for the fitting of error, while the second is concerned principally with the nature of the sampling involved. If the correction for the fitting-of-error aspect is emphasized, the two approaches appear as competitors and we must attempt to answer the question, &dquo;Which is the best method to determine
