Hi,

When I ran ordered logistic regression for ordinal outcome variable (like modified Rankin scale, 0-6), SAS gave the following note "Measures of association between the observed and predicted values were not calculated because the mean scored predicted probabilities are indistinguishable". Please explain what the note means. Even though note was presented, sas also provided statistical result. Was result correct when note also appeared? If not be correct, how do I deal with the issue? Thank you very much.

You might have more luck getting an answer if you post your question in the SAS Statistical Procedures forum.
