WebJul 18, 2024 · SPLS. SPLS, short for Sparse Partial Least Squares, is a variation on the PLS model. As stated earlier, PLS has as an objective to do dimension reduction: reducing a large number of correlated variables into a smaller number of components. The goal of SPLS is to do more than just dimension reduction.
