    Interesting how many people in the comments call Logistic Regression a regression model... Logistic Regression outputs a category, not a continuous value. To understand deeper: Logistic Regression = Linear Regression + Sigmoid (or SoftMax for multi-class) + Unit Step function Thus, for the binary case, imagine the prediction of the linear regression (a continuous value from -infinity to +infinity) that is than squeezed into the range of 0 to 1, which is not a straightforward probability, but we can interpret it that way. Lastly, a unit step function is applied (the threshold), which makes the prediction categorical. So, while part of it outputs continuous values, the final outputs is categorical and Logistic Regression is always used as a classification model in the literature.
