subroutines can also be obtained by using the NLP procedure in the SAS/OR product. The advantages of the IML procedure are as follows: You can use matrix algebra to specify the objective function, nonlinear con-straints, and their derivatives in IML modules. The IML procedure offers several subroutines that can be used to specify the

SAS Output for Repeated Measures

QMIN SAS Output for Repeated Measures - 8 The next section presents the results of tests (termed sphericity tests) on the assumptions of the repeated measures ANOVA. There are two tests, one on the transformed variables (the linear, quadratic, and cubic time variables in this case) and the second on orthogonal (i.e., uncorrelated) components.

Repeated Measures ANOVA - Stony Brook

As with any ANOVA, repeated measures ANOVA tests the equality of means. However, repeated measures ANOVA is used when all members of a random sample are measured under a number of different conditions or at different time points. As the sample is exposed to each condition, the measurement of the dependent variable is repeated.
