WebSep 8, 2024 · The usual use case for logistic regression is when your outcome, or dependent variable, is a binary categorical variable. The fact that the integers 0 and 1 are associated with the two cases is because the logistic function is mapping the result to probabilities of belonging to the class associated with the integer 1. WebLinear regression fits a straight line or surface that minimizes the discrepancies between predicted and actual output values.
