## Logistic Regression Classifier In Python

### sklearn.linear_model.LogisticRegression - scikit-learn 1.1.1 ….

Logistic Regression (aka logit, MaxEnt) classifier. In the multiclass case, the training algorithm uses the one-vs-rest (OvR) scheme if the 'multi_class' option is set to 'ovr', and uses the cross-entropy loss if the 'multi_class' option is set to 'multinomial'. (Currently the 'multinomial' option is supported only by the ....

### Logistic regression - Wikipedia.

Definition of the logistic function. An explanation of logistic regression can begin with an explanation of the standard logistic function.The logistic function is a sigmoid function, which takes any real input , and outputs a value between zero and one. For the logit, this is interpreted as taking input log-odds and having output probability.The standard logistic function : (,) is ....
