I have a very basic query. I ran a logistic model in SAS Entreprise Miner and got the output.

Let's say we have a categorical variable with 3 categories. It creates a dummy variable for 2 categories and so gives us 2 coefficients for each. When we run the same logistic equation with Base SAS using proc logistic we get only one coefficient for that categorical variable.

Are these two output saying the same thing? How does Base SAS take into account the number of categories while giving just one coefficient for the categorical variable?

Further, is there any way of getting the same kind of output with Base SAS as I got in Entreprise Miner (basically, one with different coefficients for different category)?

Any additional pointers would be greatly appreciated.

This really cannot be answered unless you post the actual code and output so we can see how SAS is interpreting the problem. – Ralph Winters May 9 '11 at 18:48

Did you add a class statement with your categorical variable? If not, SAS is interpreting it as continuous. – Aniko May 9 '11 at 19:16
Thanks Aniko..I am getting the estimates for class variables categorically separately now. – ayush biyani May 10 '11 at 5:18
