Dear R-users,
After running a logistic regression, I need to calculate OR by exponentiating
the coefficient, and then I need the 95% CL for the OR as well. For the
following example (taken from P. Dalaagard's book), what would be the most
straightforward method of getting what I need? Could anyone enlight me please?
Thank you!
