PLS Syntax - Keyword Autoscale

  { NO };

Example

AUTOSCALE=YES;

Optional keyword; use this keyword to toggle on or off the auto-scaling of the predictor variables (effects) and response variables; the default value is YES (set auto-scaling on).

When auto-scaling is requested (the default), then each column in the predictor design matrix X and matrix of dependent (response) variables Y will be divided by its respective standard deviation, and all computations will be performed on these scaled matrices X and Y. Note that the coefficients that are computed when the AUTOSCALE option is set are not the same as the standardized regression coefficients, as, for example, computed via multiple regression. For more information about auto-scaling, refer to Geladi and Kowalski(1986); see also Computational Approach in the Introductory Overview.
