mpSTATIS.rowPreproc: mpSTATIS.rowPreproc: Row Preprocessing for STATIS

In MExPosition: Multi-table ExPosition

Description

Preprocessesing of the rows of the matrix for STATIS.

Usage

mpSTATIS.rowPreproc(data, row.preprocess = 'None')

Arguments

data	Data Matrix
row.preprocess	String option with the following options: 'None'(Default), 'Profile', 'Hellinger','Center', and 'Center_Hellinger'

Details

Row Preprocessing is the first preprocessing step in STATIS. The only combination of row preprocessing that is allowed is Centering and Hellinger. The other preprocessing options cannot be combined.

If you need to create the Group Matrix into a design matrix, you can use makeNominalData which was developed by Derek Beaton.

Value

A matrix of the same dimensions as the data matrix, which is the result of the row preprocessing step chosen.
