CC {SimDesign}

Compute congruence coefficient

Description

Computes the congruence coefficient, also known as an "unadjusted" correlation or Tucker's congruence coefficient.

Usage

CC(x, y = NULL, unname = FALSE)

Arguments

x

a vector or data.frame/matrix containing the variables to use. If a vector then the input y is required, otherwise the congruence coefficient is computed for all bivariate combinations

y

(optional) the second vector input to use if x is a vector

unname

logical; apply unname to the results to remove any variable names?
