SURVEYLOGISTIC and Proportional Odds

DanielQuay — Thu, 10 Jan 2019 14:32:22 GMT

I'm having a problem running a model using proc surveylogistic.

proc surveylogistic data = source order=formatted;

class ACTIV (param=ordinal) TV_HRS(param=ordinal);

model BMIc = ACTIV|TV_HRS ;

format BMIc BMIc. ACTIV ACTIV. TV_HRS TV_HRS.;

weight WTANAL;

strata Stratumcr4;

run;

The problem I'm having is that it is not running the Proportional Odds Assumption test.

I've tried running it without the interaction variable and I still don't get this as part of my printout.

Any idea why it's not running this test? After looking for a reason all day yesterday I'm stumped.

I have the same problem. Did you figure it out?

I believe I fixed it by using the </ solution> option in the model statement.

Thank you for the reply /solution is for surveyreg but it does not work with surveylogistic.

Apologies, you are quite correct. That was the last problem I had tackled.

Regarding this one, I never did figure it out. I had to test it outside survey logistic.

I believe I graphed it, and found out that it violated the assumption so I had to change the link= option.
