Robust CAT Algorithm

Description

RobCat computes p value based on robust CAT algorithm to compare two means vectors under multivariate Behrens-Fisher problem.

Usage

RobCat(X, Y, M = 1000, alpha = 0.75)

Arguments

X

a matrix or data frame for first group.

Y

a matrix or data frame for second group.

M

iteration number and the default is 1000.

alpha

numeric parameter controlling the size of the subsets over which the determinant is minimized; roughly alpha*n, observations are used for computing the determinant. Allowed values are between 0.5 and 1 and the default is 0.75.

Details

This function computes p value based on robust CAT algorithm to compare two means vectors under multivariate Behrens-Fisher problem. When p value<0.05, it means the difference of two mean vectors is significant statistically.

Value

a list with 2 elements:

Cstat

Calculated value of test statistic

pval

The p value
