PROC LOGISTIC & Fixed Effects: Strata suppresses "Analysis of Maximum Likelihood Estimates"

[mdtr31]

Hi everyone,

I am trying to regress an ordinal variable (5 levels) on two continuous variables. In order to control for fixed effects (year & industry), I use the STRATA option. However, the result does not include any table after the "strata summary". The procedure works flawlessly without the strata option. My code is as follows and attached you may find the first 100 observations of my dataset.

ods output ParameterEstimates= ODSout_Logistic;
PROC LOGISTIC data= test ;
   model DV1=  X1  X2  / rsquare;
   strata YR  IND;
RUN;

I appreciate your help. Also, if you know any other way to control for fixed effects in a logistic regression, I would greatly appreciate that as well.

P.S. some times it works with a two-level dependent variable (DV2), but not always!

Best,

Moe
