Krzanowski's Comparison of Subspaces

Calculates statistics of Krzanowski's comparison of subspaces.

Keywords: multivariate

Usage

krzanowski.test(CA, CB, vecsA, vecsB, corr = FALSE, ...)

Arguments

CA: Matrix A
CB: Matrix B
vecsA: Vector of integers indexing the eigenvectors determining the subspace of A
vecsB: Vector of integers indexing the eigenvectors determining the subspace of B
corr: logical; if TRUE the variances of A and B are standardised
...: further arguments to be passed

Value

sumofS

metric for overall similarity with 0 indicting no similarity and a value of length(vecsA) for identical subspaces

angles

angle in degrees between each best matched pair of vectors

bisector

vector that lies between each best matched pair of vectors
