The HPPLS Procedure

supports GLM and reference parameterization for classification effects

permits any degree of interaction effects that involve classification and continuous variables

supports partitioning of data into training and testing roles

supports test set validation to choose the number of extracted factors, where the model is fit to only part of the available data (the training set) and the fit is evaluated over the other part of the data (the test set)

produces an output data set that contains predicted values and other observationwise statistics

principal components regression, which extracts factors to explain as much predictor sample variation as possible

reduced rank regression, which extracts factors to explain as much response variation as possible. This technique, also known as (maximum) redundancy analysis, differs from multivariate linear regression only when there are multiple responses.

partial least squares regression, which balances the two objectives of explaining response variation and explaining predictor variation. Two different formulations for partial least squares are available: the original predictive method of Wold (1966) and the straightforward implementation of a statistically inspired modification of the partial least squares (SIMPLS) method of De Jong (1993).
