Reference Coding for Logit Models in EM

In proc logistic you can enter code to select your 'reference' group for CLASS variables,which comes in handy for interpreting odds ratios. Can anyone tell me how to do this in EM?


Thanks.

Answer: You can't. You have the option of specifying the order of the class variable as ascending or descending based on the actual class value or label for the class- but that implies that you can only reference the first or last group by default.
