WebbYou can obtain multiple comparison tests in a repeated measures analysis by using the LSMEANS, SLICE, or LSMESTIMATE statements in several procedures. If the response is normally distributed, use PROC MIXED rather than PROC GLM. For other response distributions, use the GLIMMIX, GENMOD, or GEE procedure. did jeff shiffrin fall off roofhttp://www.math.wpi.edu/saspdf/stat/chap41.pdf did jeffrey epstein visit the white houseWebb5 dec. 2024 · You can use the REPEATED statement in PROC MIXED to specify that the measurements for individuals are autocorrelated.
