The SSM Procedure (Experimental)

MODEL response = variables ;

A MODEL statement specifies an observation equation that describes a response variable as a sum of regression effects and components defined in the program. The response variable must be a numeric variable from the input data set. The variables used in the right-hand side of the model expression can be numeric variables from the input data set, numeric variables defined by using programming statements, or names of components defined by using the COMPONENT, TREND, or IRREGULAR statements.
