Total Correlation Matrix
Description
Computes the pairwise total correlation
(totalCor) for a dataset
Usage
totalCorMat(data, base = 2.718282, normalized = FALSE)
Arguments
data
Matrix or data frame.
Should consist only of variables to be used in the analysis
base
Numeric (length = 1).
Base to use for entropy.
Defaults to exp(1) or 2.718282
normalized
Boolean (length = 1).
Should the normalized total correlation be computed?
Defaults to FALSE
Value
Returns a symmetric matrix with pairwise total correlations
