CalcICV function

Calculates the ICV of a covariance matrix.

Calculates the coefficient of variation of the eigenvalues of a covariance matrix, a measure of integration comparable to the R^2 in correlation matrices.

CalcICV(cov.matrix)

Arguments

• cov.matrix: Covariance matrix.

Returns

coefficient of variation of the eigenvalues of a covariance matrix

Details

Warning: CalcEigenVar is strongly preferred and should probably be used in place of this function.

Examples

cov.matrix <- RandomMatrix(10, 1, 1, 10)
CalcICV(cov.matrix)
