Correcting Partial, Multiple, and Canonical Correlations for Attenuation.
Edwards, Keith J.
The correction for attenuation formulas for partial, multiple, and canonical correlation coefficients are discussed and the effects of measurement errors on these statistics are explored. The notation is standardized and the derivation extended where appropriate. It is shown that as the reliabilities of the predictors become more disparate, the true contributions of each variable become more distorted. Relevant supporting formulas are included. (AE)
