In the mixed procedure code you specified a random statement and a repeated statement. The first one affects the G-matrix (and therefore the DFs), the second only affects the R-matrix. Your glimmix procedure code only contains a random statement with a residual option which therefore only affects the R-matrix and acts as … Webbtwo. PROC MIXED computes only Type I–Type III tests of fixed effects, while PROC GLM offers Types I–IV. The RANDOM statement in PROC MIXED incorporates random effects constitut-ing the vector in the mixed model. However, in PROC GLM, effects specified in the RANDOM statement are still treated as fixed as far as the model fit is con- courthouse lafayette
