Witryna6 sty 2024 · Logistic regression is linear. Logistic regression is mainly based on sigmoid function. The graph of sigmoid has a S-shape. That might confuse you and you may assume it as non-linear funtion. But that is not true. Logistic regression is just a linear model. That’s why, Most resources mention it as generalized linear model (GLM). WitrynaLogistic regression works similarly, except it performs regression on the probabilities of the outcome being a category. It uses a sigmoid function (the cumulative …
