cor.test_eq: Test for no correlation between paired sampes

In khliland/MatrixCorrelation: Matrix Correlation Coefficients

Test for no correlation between paired sampes

Description

Permutation test for squared Pearson correlation between to vectors of samples.

Usage

cor.test_eq(x, y, B = 10000)

Arguments

x	first vector to be compared (or two column matrix/data.frame).
y	second vector to be compared (ommit if included in x).
B	integer number of permutations, default = 10000.

Details

This is a convenience function combining SMI and significant for the special case of vector vs vector comparisons. The nullhypothesis is that the correlation between the vectors is +/-1, while significance signifies a deviance toward 0.

Value

A value indicating if the two input vectors are signficantly different.
