This repository contains code to reproduce results in:

L. Forzani, R. Garcia Arancibia, P. Llop and D. Tomassi, “Supervised dimension reduction for ordinal predictors” (submitted).
The main code for the proposed method is written in MATLAB. Nevertheless, some comparisons with other methods require running scripts in R. Instructions on how to use the code and reproduce results reported in the manuscript are detailed in the README.pdf file located in the main folder.
