Regression analysis … See more Now we know, in theory, what logistic regression is—but what kinds of real-world scenarios can it be applied to? Why is it useful? Logistic … See more Logistic regression is a classification algorithm. It is used to predict a binary outcome based on a set of independent variables. Ok, so … See more In this post, we’ve focused on just one type of logistic regression—the type where there are only two possible outcomes or categories (otherwise known as binary regression). In fact, … See more 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.
