A Simple Explanation of Partial Least Squares

The idea behind principal component regression is to rst perform a principal component analysis (PCA) on the design matrix and then use only the rst kprincipal components to do the regression. To understand how it works, it helps to rst understand PCA. De nition 4. A matrix A is said to be orthogonally diagonalisable if there are an orthogonal
