In okayaa/MT: Methods in Mahalanobis-Taguchi (MT) System

Description

generates_dimensionality_reduction_function returns the data transformation function for the Recognition-Taguchi (RT) method based on the unit_space_data. The function reduces the dimensionality of data into 2 synthetic variables.

Usage

generates_dimensionality_reduction_function(unit_space_data)

Arguments

unit_space_data

Matrix with n rows (samples) and p columns (variables). Data to generate the unit space. All data should be continuous values and should not have missing values.

Value

Function is returned which takes an n x p matrix as an (only) argument and returns a dimensionality-reduced n x 2 data frame with named columns; Y_1 and Y_2.
