WebLogistic regression, despite its name, is a classification algorithm rather than regression algorithm. Based on a given set of independent variables, it is used to estimate discrete value (0 or 1, yes/no, true/false). It is also called logit or MaxEnt Classifier. Web10 apr. 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 ...
