I am looking for a way to pool the likelihood ratio test (test3 statistics for some categorical covariates).

 

My estimates and statistics for the imputed datasets are:

 

proc glimmix data=Edeathm2;
class study issstg mmtg;
model pdgrp1 = raceg hbcatg eort mmtg mprtg issstg fraig
cyto2rg diabflag pltg ldhg novel/s oddsratio covb;
random intercept / subject=study;
by _Imputation_;
ods select ParameterEstimates CovB FitStatistics;
ods output ParameterEstimates=lgparms CovB=lgcovb ;
ods output tests3=lrtest;
run;

 

How can I generate the pooled likelihood ratio tests for my covariates with proc mianalyze?

Thanks.

It is suggested that you combine the actual Chi-Square statistics.  Paul Allison has a macro on his website
