RcppgCov: Gini Distance Covariance Statistics

In GiniDistance: A New Gini Correlation Between Quantitative and Qualitative Variables

Description

Computes Gini distance covariance statistics, in which Xs are quantitative, Y are categorical, alpha is an exponent on Euclidean distance and returns the measures of dependence.

Usage

  RcppgCov(x, y, alpha)

Arguments

x	data
y	label of data or univariate response variable
alpha	exponent on Euclidean distance, in (0,2]

Details

RcppgCov compute Gini distance covariance statistics. It is Rcpp version of gCov.

Value
