Hi all,
In SAS9.4 it is possible to run proc logistic with non-proportional odds by specifying '/unequalslopes' at the end of the model statement.
I now need to do this in an earlier version of SAS in which this option is not available.
Any suggestions how I can do this?
thank you!
What version of SAS do you have?
And why does your title talk about PROC SQL?
very sorry - should be proc logistic.
I have sas9.3, but it pre-dates the unequal slopes option.
What does this have to do with PROC SQL?
The addendum at the end of this note on the partial proportional odds model shows how it can be done using PROC NLMIXED. Note that there have been at least six releases of SAS since 9.3. I strongly encourage you to upgrade to take advantage of the many new features that have been added over the years.
Thank you, StatDave,
I would dearly love to upgrade to the newest, shiniest, version of SAS, but alas my employer is a government agency with a ZBB for stuff they don't understand. Thus I suffer.
Could you try PROC PROBIT ? or PROC GENMOD for GEE model ?
