The GLM Procedure 
MODEL Statement 
The MODEL statement names the dependent variables and independent effects. The syntax of effects is described in the section Specification of Effects. For any model effect involving classification variables (interactions as well as main effects), the number of levels cannot exceed 32,767. If no independent effects are specified, only an intercept term is fit. You can specify only one MODEL statement (in contrast to the REG procedure, for example, which allows several MODEL statements in the same PROC REG run).
Table 39.5 summarizes options available in the MODEL statement.

The options available in the MODEL statement are described in the following list.
specifies that the estimable functions should be displayed as an aliasing structure, for which each row says which linear combination of the parameters is estimated by each estimable function; also, this option adds a column of the same information to the table of parameter estimates, giving for each parameter the expected value of the estimate associated with that parameter. This option is most useful in fractional factorial experiments that can be analyzed without a CLASS statement.
specifies the level of significance for % confidence intervals. By default, is equal to the value of the ALPHA= option in the PROC GLM statement, or 0.05 if that option is not specified. You can use values between 0 and 1.
produces confidence limits for individual predicted values for each observation. The CLI option is ignored if the CLM option is also specified.
produces confidence limits for a mean predicted value for each observation.
produces confidence limits for the parameter estimates (if the SOLUTION option is also specified) and for the results of all ESTIMATE statements.
displays the general form of all estimable functions. This is useful for determining the order of parameters when you are writing CONTRAST and ESTIMATE statements.
displays the Type I estimable functions for each effect in the model and computes the corresponding sums of squares.
displays the Type II estimable functions for each effect in the model and computes the corresponding sums of squares.
displays the Type III estimable functions for each effect in the model and computes the corresponding sums of squares.
displays the Type IV estimable functions for each effect in the model and computes the corresponding sums of squares.
adds measures of effect size to each analysis of variance table displayed by the procedure, except for those displayed by the TEST option in the RANDOM statement and by CONTRAST statements with the E= option. The effect size measures include the intraclass correlation and both estimates and confidence intervals for the noncentrality for the test, the semipartial , and the partial . For more information about the computation and interpretation of these measures, see the section Effect Size Measures for F Tests in GLM.
produces the hypothesis tests associated with the intercept as an effect in the model. By default, the procedure includes the intercept in the model but does not display associated tests of hypotheses. Except for producing the uncorrected total sum of squares instead of the corrected total sum of squares, the INT option is ignored when you use an ABSORB statement.
displays the augmented inverse (or generalized inverse) matrix:
The upperleft corner is the generalized inverse of , the upperright corner is the parameter estimates, and the lowerright corner is the error sum of squares.
omits the intercept parameter from the model. The NOINT option is ignored when you use an ABSORB statement.
suppresses the display of univariate statistics. You typically use the NOUNI option with a multivariate or repeated measures analysis of variance when you do not need the standard univariate results. The NOUNI option in a MODEL statement does not affect the univariate output produced by the REPEATED statement.
displays observed, predicted, and residual values for each observation that does not contain missing values for independent variables. The DurbinWatson statistic is also displayed when the P option is specified. The PRESS statistic is also produced if either the CLM or CLI option is specified.
tunes the sensitivity of the regression routine to linear dependencies in the design. If a diagonal pivot element is less than as PROC GLM sweeps the matrix, the associated design column is declared to be linearly dependent with previous columns, and the associated parameter is zeroed.
The value adjusts the check to the relative scale of the variable. The value is equal to the corrected sum of squares for the variable, unless the corrected sum of squares is 0, in which case is 1. If you specify the NOINT option but not the ABSORB statement, PROC GLM uses the uncorrected sum of squares instead.
The default value of the SINGULAR= option, , might be too small, but this value is necessary in order to handle the highdegree polynomials used in the literature to compare regression routines.
produces a solution to the normal equations (parameter estimates). PROC GLM displays a solution by default when your model involves no classification variables, so you need this option only if you want to see the solution for models with classification effects.
displays the sum of squares associated with Type I estimable functions for each effect. These are also displayed by default.
displays the sum of squares associated with Type II estimable functions for each effect.
displays the sum of squares associated with Type III estimable functions for each effect. These are also displayed by default.
displays the sum of squares associated with Type IV estimable functions for each effect.
displays the tolerances used in the SWEEP routine. The tolerances are of the form C/USS or C/CSS, as described in the discussion of the SINGULAR= option. The tolerance value for the intercept is not divided by its uncorrected sum of squares.
displays the augmented crossproducts matrix:
tunes the sensitivity of the check for estimability for Type III and Type IV functions. Any element in the estimable function basis with an absolute value less than the ZETA= option is set to zero. The default value for the ZETA= option is .
Although it is possible to generate data for which this absolute check can be defeated, the check suffices in most practical examples. Additional research is needed in order to make this check relative rather than absolute.
