Is there a way to get confidence intervals around an ordered regression like
polr() in the MASS package?
Please don't both ask the author directly *and* post to a forum.
The answer is the same as the one I sent you directly.
- For what do you want CIs, and why? The fits/predictions are
probabilities, and CIs for probabilities are rarely useful.
- You can do this by simulation, and simulate() has a polr method.
