WebAug 3, 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. http://whatastarrynight.com/machine%20learning/operation%20research/python/Constructing-A-Simple-Logistic-Regression-Model-for-Binary-Classification-Problem-with-PyTorch/
