Linear vs logistic regression example
NettetLogistic Regression. Logistic regression aims to solve classification problems. It does this by predicting categorical outcomes, unlike linear regression that predicts a continuous outcome. In the simplest case there are two outcomes, which is called binomial, an example of which is predicting if a tumor is malignant or benign.
