I used PROC LOGISTIC to run a cumulative logit model for ordinal response. The dependent variable has 3 levels: group=1, group=2, and group=3. For the cumulative logit model here, the predicition is for the probability in the lower category (group 1 vs group 2, 3, and group 1, 2 vs group 3).
I don't undertand the meaning of the intercepts, which are produced as:
Intercept: group=3 2.325
Intercept: group=2 5.273
I am very confused with the meaning of intercepts here. Can you please help?

Have you tried looking at the Cheese example in the SAS Doc? Example 51.3 in SAS 9.2 documentation, similar situation or are you unsure how to specifically interpret your results?
