The partial least squares method For a long time, the boundaries between the methods of model type and understanding of the share is very clear. The partial least squares rule them organically, in an algorithm, can simultaneously achieve regression (multivariate linear regression), simplify the ...

plsregress uses the SIMPLS algorithm [1]. If the model fit includes the constant term (intercept), the function first centers X and Y by subtracting the column means to get the centered predictor and response variables X0 and Y0, respectively. However, the function does not rescale the column...

Since partial least squares (PLS) is the soft sensor algorithm used to evaluate the performance of the variable selection methods, and in fact several methods evaluated in this work are also based on PLS, here we briefly review the PLS algorithm. PLS is a well-known multivariate statistical te...
