WebThe defining characteristic of the logistic model is that increasing one of the independent variables multiplicatively scales the odds of the given outcome at a constant rate, with each independent variable having its own parameter; for a binary dependent variable this generalizes the odds ratio. WebApr 10, 2024 · The goal of logistic regression is to predict the probability of a binary outcome (such as yes/no, true/false, or 1/0) based on input features. The algorithm models this probability using a logistic function, which maps any real-valued input to a value between 0 and 1. Since our prediction has three outcomes “gap up” or gap down” or “no ...
