FAQ: How do I interpret odds ratios in logistic regression?

WebThe coefficient returned by a logistic regression in r is a logit, or the log of the odds. To convert logits to odds ratio, you can exponentiate it, as you've done above. To convert logits to probabilities, you can use the function exp (logit)/ (1+exp (logit)). However, there are some things to note about this procedure.
