I've been using R to do logistic regresssion, and that's working
well, but there are two things I haven't figured out how to do.
(1) Is there some pre-existing function that will let you compute the
odds ratios and confidence intervals for them for a specific fit. I know
how to do this manually or even write a function that I can call with
the coefficients and se, but extending the printing function was a
little more work than I expected.
I.e. I'm looking for something where you'd type
Coefficient Odds ratio 95% CI
XXX 5.2 1.5 7.2
(2) I'd like to compute goodness-of-fit statistics for my fit
(Hosmer-Lemeshow, Pearson, etc.). I didn't see a package that
did this. Have I missed one?
