WitrynaLogistic Regression is a classification algorithm and not a regression algorithm. It is used to estimate discrete values (like 0 or 1, True or False, Yes or No) based on a given set of independent variables. Logistic Regression produces results in a binary format that is used to predict the outcome of a categorical dependent variable. WitrynaThe linear regression that we previously saw will predict a continuous output. When the target is a binary outcome, one can use the logistic function to model the probability. … lyrics king of anythingWitrynaThe logit in logistic regression is a special case of a link function in a generalized linear model: it is the canonical link function for the Bernoulli distribution.
