RperT2: Robust Permutation Hotelling T^2 Test in High Dimensional Data

Description

Robust Permutation Hotelling T^2 Test for Two Independent Samples in high Dimensional Data

Usage

RperT2(X1, X2, alpha = 0.75, N = 100)

Value

a list with 2 elements:

T2

The calculated value of Robust Hotelling T^2 statistic based on MRCD estimations

p.value

p value obtained from test process

Arguments

X1

the data matrix for the first group. It must be matrix or data.frame.

X2

the data matrix for the first group. It must be matrix or data.frame.

alpha

numeric parameter controlling the size of the subsets over which the determinant is minimized. Allowed values are between 0.5 and 1 and the default is 0.75.

N

the permutation number
