The HPFMM Procedure
Parameterization of Model Effects
PROC HPFMM constructs a finite mixture model according to the specifications in the CLASS
, MODEL
, and PROBMODEL
statements. Each effect in the MODEL
statement generates one or more columns in the matrix 
for that model. The same matrix applies to all components that are associated with the MODEL
statement. Each effect in the PROBMODEL
statement generates one or more columns in the matrix 
from which the linear predictors in the model for the mixture probability models is formed. The same matrix applies to all components.
The formation of effects from continuous and classification variables in the HPFMM procedure follows the same general rules and techniques as for other linear modeling procedures. For information about constructing the model effects, see the section Specification and Parameterization of Model Effects in SAS/STAT 14.1 User's Guide: High-Performance Procedures.
