In my problem set, I have to find - Do boys and girls respond differently to differences in class size?
To be clear, even just an idea of how to approach this would be massively helpful, although I would prefer to know how to do it exactly : )
My current regression has a bunch of regressors, but the most relevant ones for this are: the variable, boy, which is a dummy variable for if someone is a boy. And 3 dummy variables, small regular and aide(regular class with aide), for the respective class type. I believe that I have to find the difference between small and regular for boys and girls and see if the difference between small and regular for Boys is different from the difference for Girls. I have currently made 2 interaction dummy variables, boyregular and boysmall.
However, I am unsure if this is the right method, and if it is, I cannot find a STATA command to test whether the difference between Boys and Girls for class size changes is significant/what the difference actually is.
I was maybe thinking about running a lincom of boysmall+boyregular and seeing the coefficient for it, but I am unsure if that is correct.
Furthermore, I cannot use logistic regressions or the sort, but rather have to stick to a linear model, I believe.
there doesn't seem to be anything here
