How do you find the odds ratio from logistic regression coefficient?
For binary classification problems, the coefficients for linear models are displayed in link space, as logit (or "logodds") coefficients. Once the coefficient CSV is exported, you can convert the coefficients to odds ratios by exponentiating them. For example, in Excel that would be =exp(<coef>).
How to get odds ratio from logistic regression in Stata?
You can obtain the odds ratio from Stata either by issuing the logistic command or by using the or option with the logit command.
How to calculate odds ratio?
In a 2-by-2 table with cells a, b, c, and d (see figure), the odds ratio is odds of the event in the exposure group (a/b) divided by the odds of the event in the control or non-exposure group (c/d). Thus the odds ratio is (a/b) / (c/d) which simplifies to ad/bc.
How to interpret odds ratio in ordered logistic regression?
The interpretation would be that for a one unit change in the predictor variable, the odds for cases in a group that is greater than k versus less than or equal to k are the proportional odds times larger.
How to convert logistic regression coefficient to odds ratio in R?
The 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)) .
