WitrynaTo find the log-odds for each observation, we must first create a formula that looks similar to the one from linear regression, extracting the coefficient and the intercept. log_odds = logr.coef_ * x + logr.intercept_. To then convert the log-odds to odds we must exponentiate the log-odds. odds = numpy.exp (log_odds)

WitrynaLogistic regression is a special case of the generalized linear regression where the response variable follows the logit function. The input of the logit function is a probability p, between 0 and 1. The odds ratio for probability p is defined as p/ (1-p), and the logit function is defined as the logarithm of the Odds ratio or log-odds.
