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. WebWe consider a two-step estimation approach, where the first step is to substi-tute least squares estimates ~m[x,m[y![@(i1 n z'z # 1 (n z'~x,y! into ~3! and ~5! to obtain a lower dimensional errors-in-variables model, and the sec-ond step is to estimate b using high-order sample moments of y i z i m[y and x i z i m[x+ Estimates of a are then ...
