Hello! This is my first post, so I hope I've come to the right place. I have a rather simple question, which is does PROC ADAPTIVEREG have the capability to model nominal (multiple valued, non-ordinal like the name of a country, a color, etc.) variables, and if so, how would I be able to do it? This manual contains a ouple of references (pictured in the top half of the attached picture), however no examples or statements to tell the procedure that my predicted value should be nominal. Also, this manual curiously omits (pictured in the bottom half of the attached picture) ADAPTIVEREG in the list of procedures capable of dealing with multinomial data. I've tried everything, but in the cases of categorical variables SAS keeps telling me that the dependent variable has to have two values. Is there any way to make this work? P.S. I have an assignment specifically on the application of MARS in specific fields, so unfortunately simple multinomial regression analysis isn't an option for me.
