Changes and Enhancements to SAS/STAT Software in V7 and V8

GLM Procedure

The new ALPHA= option in the PROC GLM statement specifies the level of significance for confidence intervals computed from the LSMEANS, MEANS, MODEL, and OUTPUT statements. The ALPHA= option in all of these statements overrides the ALPHA value in the PROC GLM statement. The NAMELEN= option enables you to specify the length of effect names to be between 20 and 200 characters

The ALIASING option in the MODEL statement specifies that the estimable functions should be displayed as an aliasing structure, such that each row specifies the linear combination of the parameters estimated by each estimable function. This option is very useful in fractional factorial experiments that can be analyzed without a CLASS statement. The CLPARM option in the MODEL statement produces confidence limits for the parameter estimates (when you specify the SOLUTION option) and for the results of all ESTIMATE statements.
