multiple outcome comparison with proc mixed

superbibi — Fri, 01 Feb 2019 19:22:39 GMT

Hi SAS users,

I am trying to use proc mixed to run repeated measurement analyses for 5 continuous outcomes comparing two independent groups.

I am also want to do adjustment (such as Tukey) because I am testing several outcomes.

How can I write the code using proc mixed procedure to achieve those objectives?

Thank you.

Are the observations correlated across the responses? ie, did you measure the 5 outcomes on the same experimental unit, with units divided into two group? A repeated measures model might work then. You can use PROC GLIMMIX, fitting a separate mean to each level of response and you could compare the means using an LSMEANS statement with SLICEDIFF= and the appropriate ADJUST=.

Something like

proc glimmix data=test;
class group resp;
model y=group*resp;

random int / subject=id;
lsmeans group*resp / slicediff=resp adjust=tukey;
run;

might work. MIXED does not have the ability to adjust across only the sliced tests.
