Bob asked a good question. I too have been unable to find an

equivalent of the SAS Proc Catmod in SPSS. Any ideas?

SPSS's Multinomial Logit procedure in the Regrssion Module is equivalent

to CATMOD, but there is no equivalent in SPSS for the conditional

multinomial logit run under PHreg is SAS.

Lawrence,

Thanks for your response. Could you try translating that into English for

me? I think I bought the Regression Module (but I'm not sure how to verify

that). I do have a Regression option from the Analyze pulldown menu, but I

don't see any choice that looks like Multinomial Logit. Does that mean I

don't have the Regression module?

There should be a Multinomial Logistic selection under

Analyze -> Regression (in versions 10.0.7 and 11.0). If

that does not appear, my guess is you don't have the add-

on installed. The SPSS website does indicate that this

procedure is part of the Regression Models add-on. Check

to make sure you have correctly installed the add-on.

Under Analyze -> Regression, you also should see

selections like Ordinal, Probit, and Nonlinear.

Hope this helps,

I am not a statistician, which will become immediately obvious. I have just

loaded SPSS 11 and can see that it is much more user-friendly than SAS which

I have use, fitfully, for many years. One of the procedures I have relied

on in SAS is CATMOD. It let me do a GLM like analysis (two-way ANOVA stuff

such as compare main effects and test for interactions) on percentage data.

I don't see an equivalent in SPSS. Is there one? If so what is it called?

If not what is the recommended way in SPSS to analyze percentage data that

is grouped by multiple categories, each with multiple levels?

Thanks, Bob.
