NettetIf I had to guess, "classification" mostly occurs in machine learning context, where we want to make predictions, whereas "regression" is mostly used in the context of inferential statistics. I would also assume that a lot of logistic-regression-as-classification cases actually use penalized glm, not maximum likelihood (iirc that's actually the ...

Interpreting the coefficients of a logistic regression model can be tricky because the coefficients in a logistic regression are on the log-odds scale. This means the interpretations are different than in linear regression.
