Witryna27 sie 2007 · However, in logistic regression it refers to interaction as departure from multiplicativity. Rothman has argued that interaction estimated as departure from additivity better reflects biologic interaction. So far, literature on estimating interaction on an additive scale using logistic regression only focused on dichotomous … Witryna2 lip 2024 · The regression output would lead us to believe there is no interaction. Let’s do the linearity check: interact_plot(model_2, pred = x_2, modx = w, linearity.check = TRUE, plot.points = TRUE) This is a striking example of the assumption being violated. At both levels of \ (W\), the relationship between \ (X_2\) and the response is non-linear.
