WebIt can model random and mixed effect data, repeated measures, spacial data, data with heterogeneous variances and autocorrelated observations. The MIXED procedure is more general than GLM in the sense that it gives a user more flexibility in specifying the correlation structures, particularly useful in repeated measures and random effect models. girls in freaky friday music video
