:         This directory contains a simple program written in portable
:         Fortran 77 to derive QSAR models via regression analysis.
:         The analysis can be performed by ordinary least squares (OLS),
:         principal components (PCR) or partial least squares (PLS).
:         Both the NIPALS and SIMPLS algorithms for PLS are implemented;
:         see the source code for further details. "Leave-1-out" cross-
:         validation can be performed for all three types of regression.
:         For OLS and PCR, variable selection can be run via simulated
