Summary
PLS regression is a regularized robust alternative to multiple linear regression when dealing with multicollinearity. PLSR is very useful in particular in the analysis of wide data tables (p> n).
This course which aims to be pedagogic through many applications in R will provide basic elements useful to the understanding of the methods from a theoretical point of view.
PLS regression will be compared to other regularized alternatives such as principal component regression, ridge regression, Lasso and generalized Lasso. Extensions of PLS regression to discriminant analysis (PLS-DA Barker& Rayens), multiblocs, sparsity (variable selection), nonlinearity using kernels or splines, and generalized linear models will be fully described.
