WebWith interactions, it’s more complicated: y = 0 + 1age + 2male + 3male age But similar in the sense that the e ect of age now depends on sex; or the other way around, the e ect of sex depends on age With interactions, taking the derivative still helps with interpretation: @E[yjage;male] @age = 1 + 3 male Centering also helps with parameter ...

WebWe can also compute the ratio of odds ratios and show that it reproduces the estimate for the interaction. ratio of odds ratios: (3.677847/2.609533)/ (1.424706/.1304264) = .1290242 The one nice thing that we can say about working in odds ratio metric is the odds ratios remain the same regardless of where we hold the covariate constant. WebFirst of all, a common problem with margins is that you cannot use generated interactions. You have to let STATA compute those. For instance, consider the following model: Y= a + b1X1 + b2X2 +...
