Hi,

I have used 3 logit equation and used "suest" command to combine parameter estimate and covariance matrices. Now, I want to use "Predict" command to estimate predicted probability.
When I code:

predict probab if e(sample) == 1

The values I am getting are greater than one. Hence, they are not predicted probability. I need the predicted probability to calculate concordance Index.
Please help me to calculate the predicted probability or concordance index directly.

Very Thanks in advance.
