Regression analysis of linear composite variance

The problem of defining and determining the effective contribution of a component variable to the variance of a composite is briefly reviewed. Another method of dealing with this problem is proposed and illustrated with analysis of a three-component problem. The proposed method is based on systematic application of a series of regressions and is restricted in application to positive manifold systems.This study was performed at Personnel Laboratory, WADD, Lackland AFB, Texas, under ARDC Project 7717, Task 87003.
