The MODEL statement names the dependent variable and the independent effects. Only one MODEL statement is allowed. The specification of effects
and the parameterization of the linear model are the same as in the GLM procedure; see ChapterĀ 45: The GLM Procedure for further details.
The following option can be used in the MODEL statement:

NOINT

omits the intercept term from the model. Often, this omission also changes the total sum of squares in the ANOVA and the value
of R square to forms of these statistics that are not corrected for the mean. However, if the model is determined to contain
an implicit intercept, in the sense that the allones intercept vector is in the column space of the design, then the usual
meancorrected forms of these statistics are used.
