Nettet31. okt. 2024 · Interactions in the linear probability model appears to be a good approximation of interactions in logistic regression as long as the variables involved are dummy variables. As soon as a continuous variable is involved in the interaction, LPM interactions can deviate more or less substantially from their logistic counterpart.
