I'm running logit in JMP. My understanding is that if you exponentiate the coefficients, you get the change in odds ratios from a 1 unit change in X.
This works perfectly for continuous independent variables, but not for nominal (0,1) independent variables. Example below:
For parameter estimates I'm getting:
Level1 /Level2 Odds Ratio
Male Female 0.6416016
Female Male 1.5585996
Shouldn't my odds ratio for males be exp(-1.516621)=0.220486 and for females be exp(0.20461503)=1.2270525?
Befuddled by this. Would really appreciate some help. Thanks!
