Proc mianalyze for type 3 tests

ProfB — Thu, 20 Sep 2018 22:42:31 GMT

I'm trying to pool type 3 tests from a regression model using proc genmod, across 10 imputed data sets. Is there a macro to leverage the ods type3 output table I can use to generate a pooled estimate of the p-value (for example, for "X1" in the code snippet below)?

proc genmod data=data plots=(dfbetacs); 
 class id time;
 model y=time X1 time*X1 X2*time X3*time /noint dist=normal link=identity id=studyid type3;
 repeated subject=id/type=ind ecovb;
 weight &weight;
 ods output GEEEmpPEst=emp_est type3=type3table; ;
 by _imputation_;
run;

proc mianalyze parms (classvar=level)= emp_est;
 class time ;
 modeleffects time*X1; 
run;

While there is no way to combine the Type3 tests in MIANALYZE you can combine the Chi-Square statistics themselves from the Type3 tests using the COMBCHI macro found on Paul Allison's web site.
