QSAR Modeling with Multiple Algorithms: MLR, PLS, and Random Forest

v1.0.0 · Apr 2, 2024 · MIT + file LICENSE

Description

Quantitative Structure-Activity Relationship (QSAR) modeling is a valuable tool in computational chemistry and drug design, where it aims to predict the activity or property of chemical compounds based on their molecular structure. In this vignette, we present the 'rQSAR' package, which provides functions for variable selection and QSAR modeling using Multiple Linear Regression (MLR), Partial Least Squares (PLS), and Random Forest algorithms.
