An alternative formula for the true correlation of initial values with gains.

Abstract

In the Journal of Experimental Psychology, 1924, VII., 321, there was obtained a formula to give correct correlations between gains and initial values, which in a raw state are vitiated by errors of measurement producing a complication of the attenuation effect. The object of this short note is to give an alternative to equation 11 in that paper. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
