spdCor {nda}

Calculating semi-partial distance correlation of columns of a matrix

Description

Calculating semi-partial distance correlation of two columns of a matrix for Generalized Network-based Dimensionality Reduction and Analysis (GNDA).

The calculation is very slow for large matrices!

Usage

spdCor(x)

Arguments

x

a a numeric matrix, or a numeric data frame

Value

Semi-partial distance correlation matrix of x.
