In multicross: A Graph-Based Test for Comparing Multivariate Distributions in the Multi Sample Framework

Description

When the MCM/MMCM tests reject the null, class selection can help determine which of the K classes are the likely contributors for rejection

Usage

select_class(data_list, level)

Arguments

data_list	is list of multifeature matrices corresponding to the K different classes, so each element of the list is a matrix, for a total of K matrices.
level	is the cutoff value (alpha) for hypothesis testing

Value

A table of pairwise comparisons among the K classes, to further probe which class influences the rejection of the null the most. No p-value adjustment is made to these reported p-values

Examples

# Simulation Example when the user wants to test whether K=3 multivariate distributions are equal:
X1 = MASS::mvrnorm(10,rep(0,4),diag(2,4),tol=1e-6, empirical=FALSE, EISPACK=FALSE)
X2 = MASS::mvrnorm(10,rep(0,4),diag(1,4),tol=1e-6, empirical=FALSE, EISPACK=FALSE)
X3 = MASS::mvrnorm(10,rep(0,4),diag(3,4),tol=1e-6, empirical=FALSE, EISPACK=FALSE)
select_class(list(X1,X2,X3), 0.05)
