Calculate Reference Eigenvalues for the Empirical Kaiser Criterion

Description

Calculate Reference Eigenvalues for the Empirical Kaiser Criterion

Usage

faEKC(R = NULL, NSubj = NULL, Plot = FALSE)

Arguments

R	Input correlation matrix.
NSubj	Number of subjects (observations) used to create R.
Plot	(logical). If Plot = TRUE the function will plot the observed and reference eigenvalues of R.
