Dear Statalists,
I am estimating a model with interaction terms, like y=a+bx+cz+dx*z, where x is a continuous variable and z is a dummy variable. Assums both b(the coefficient of the continuous variable) and d(the coefficient of the interaction term) are significant. I think that b is the effect of x on y when z=0, and d is the difference in the effect of x on y between z=0 and z=1. So can I say that the effect of x on y (when z=1) is equal to b+d?
Many thanks!
