MWT: Modified Williams Transformation

Description

MWT returns a matrix after implementing the modified Williams transformation

Usage

MWT(X)

Arguments

X

A matrix object. In general, X stands for the design matrix, e.g. an LHD or a GLP design.

Value

If all inputs are logical, then the output will be a matrix whose sizes are the same as input matrix. Note that the output matrix is not an LHD.
