I am using DCON with a distal outcome. I wish to include two other covariates in the model - can you advise as to which Auxiliary command to use or should these covariates be specified in the model command?
Also I note the error message that DCON cannot be used with KNOWNCLASS - is there a workaround this?
I used auxiliary command and dcat/dcon to compare frequencies and proportions of distal outcome variables. However, the result was far from expected. The results of auxiliary variables were not consistent with cross-tabulations and mean comparisons using most likely class membership from the same input program. The entropy was .885, so I don't think the uncertainty came into play. One thing I'm suspicious was the class order switched. There were three classes, in the descending order of 1-2-3 in terms of class size. However, in the distal outcome section of output, the classes were in the ascending order of 3-1-2 in terms of approximate SE. In addition, if I switched the order by its approximate SE, the result was consistent with crosstab and mean comparison using most likely class membership.
1. Is it possible that classes switch in distal outcome output using dcon/dcat option? 2. If so, how can we check the correct order of class. 3. If not, could you guess what could possibly went wrong? 4. In this case, with entropy .885, can I report proportion and mean comparisons based on most likely class membership, instead of using auxiliary command? 5. Could you suggest any better ways?
