WebbModels fit with PROC GLIMMIX can have none, one, or more of each type of random effect. Note that an R-side effect in PROC GLIMMIX is equivalent to a REPEATED effect in the MIXED procedure. The R-side covariance structure in PROC GLIMMIX is the covariance structure that you formulate with the REPEATED statement in the MIXED procedure. WebbIf you specify the INFLUENCE option without further suboptions, PROC MIXED computes single-case deletion diagnostics and influence statistics for each observation in the data set by updating estimates for the fixed-effects parameter estimates, and also the residual variance, if it is profiled.

WebbThere are two ways to deal with this correlation. The Marginal Model One is to alter the covariance structure of the residuals. What this means is that instead of assuming that all observations are independent, as you do in a linear model, you assume the residuals from a single subject are related. Their covariances are non-zero. WebbYou can perform a traditional two-way analysis of variance of these data with the following PROC MIXED statements: proc mixed data=heights; class Family Gender; model Height = Gender Family Family*Gender; run; The PROC MIXED statement invokes the procedure.
