PLS Syntax - Keyword Intercept

  { INCLUDE };

Example

INTERCEPT = EXCLUDE;

Optional keyword; specify whether or not the intercept (constant) is to be included in the model (i.e., a parameter is to be estimated for the intercept); the default is INTERCEPT= EXCLUDE.

The intercept in PLS models (see the Introductory Overview) is handled in a different manner than in general linear models (see also the General Linear Model (GLM) Introductory Overview section). If INTERCEPT=EXCLUDE is specified, all columns of the (predictor) design matrix X and matrix of dependent or response variables Y are centered at their means, and the intercept term is excluded from the model. If INCLUDE is specified, these matrices are not centered and the intercept term is included in the model. For additional details, see also the Computational Approach section in the Introductory Overview.

Applies to. PLS (keyword has different "meaning" in GLM, GRM, GLZ).
