Ordered Probit (similar to Ordered Logit): How to graph?
Hi!
I have just run a oprobit and am curious about how to graph the results.
From there I did this and simply graphed the results. However, I was expecting an S-shaped graph.
Did I graph the interpretation correctly? What else should I/what should I have done instead? (picture is best I could do with sizing limits)
Hi!
I have just run a oprobit and am curious about how to graph the results.
Code:
. oprobit numrate NSPFrac
Iteration 0: log likelihood = -111627.39
Iteration 1: log likelihood = -111415.17
Iteration 2: log likelihood = -111415.17
Ordered probit regression Number of obs = 69358
LR chi2(1) = 424.44
Prob > chi2 = 0.0000
Log likelihood = -111415.17 Pseudo R2 = 0.0019
