The HPPLS Procedure

By default, the HPPLS procedure produces the "Percent Variation Accounted for by Extracted Factors" table to display just the amount of predictor variation and response variation that are accounted for by each factor. If you specify the VARSS option in the PROC HPPLS statement, the HPPLS procedure also produces the "Model Effect Percent Variation Accounted for by Extracted Factors" table and the "Dependent Variable Percent Variation Accounted for by Extracted Factors" table to display the amount of variation that is accounted for in each response and predictor, in addition to the average response and predictor sum of squares that are accounted for by each successive factor.
