Is there a simple rule for interpretation of Interactions (and their directions) in binary logistic regression? [duplicate] This question already has an answer here: I have a binary logistic regression with Y (a disease) and 5 independent variables (and some of their 2-sided interactions which did not cause multicollinearity). All of my single IVs significantly predict Y: A: positive beta for males (males are more likely to get affected) B: a positive beta (older people are more likely to be affected) C (yes/no): a positive beta for smoking (smokers are more likely to be affected) D (continuous): a positive beta (more traumatic patients are more likely to have disease) E (yes/no): a Negative beta for treatment (treated cases were less likely to have diseases). Now 4 interactions are significant and I want to interpret them. I know I should state that in a significant interaction, I should say that the effect of variable A on Y differed for B(1) and B(2). For example the effect of age on disease differed in males and females. But I don't know in which class (males or females), it was greater, and I don't know how to determine it. The significant interactions and their direction of betas are as follows: 4 by 3: positive beta 4 by 5: positive beta 1 by 2: Negative beta 3 by 2: Negative beta.
