Webb3 aug. 2024 · A logistic regression model provides the ‘odds’ of an event. Remember that, ‘odds’ are the probability on a different scale. Here is the formula: If an event has a probability of p, the odds of that event is p/ (1-p). Odds are the transformation of the probability. Based on this formula, if the probability is 1/2, the ‘odds’ is 1.
