Mianalyze on GLM contrasts ?

[Giampaolo]

Hi,

I would like to pool the results of  contrasts statements after multiple imputation. Is there a way to do it? 

Thank you 

My code is the following:

proc glm data = MI_dataset outstat= stat;
by _imputation_;
class &catvar;
model iNPI=&catvar;
contrast 'linear' &catvar -3 -1 1 3;
contrast 'quadratic' &catvar 1 -1 -1 1;
contrast 'cubic' &catvar -1 3 -3 1;
run;quit;

Because MIANALYZE only works and point estimates and their standard errors, you would need to convert these to ESTIMATE statements.

See the example at the bottom of this usage note for how to combine the ESTIMATE statements.

Thank you!

Is it possible then to use the estimate statement, instead of the contrast statement, to test for a trend ? As in my code obtained from  https://support.sas.com/kb/22/912.html?

Hello, I am also facing the same issue; testing for trend with multiply imputed data. How did you solve that?
