Description

twoStepTransform is a transformation that can be applied to a matrix of data. The resulting matrix is both subject-centered and bias corrected, a technique called the CM technique \insertCiteb12,c05,m08superb

Usage

twoStepTransform(dta, variables)

Arguments

dta	a data.frame containing the data in wide format;
variables	a vector of column names on which the transformation will be applied. the remaining columns will be left unchanged
