TīmeklisThe odds ratio for your coefficient is the increase in odds above this value of the intercept when you add one whole x value (i.e. x=1; one thought). Using the menarche data: exp (coef (m)) (Intercept) Age 6.046358e-10 5.113931e+00. We could interpret this as the odds of menarche occurring at age = 0 is .00000000006.
