Hi,

I am running a regression using the following code:
Code:
reghdfe incvote i.X controls, absorb(i.country i.region)
where incvote is a binary variable and the X variable is categorical with values 0, 1, and 2. The frequencies of these categories are respectively 1700, 5100, and 1900. Do the stark differences in the sizes (group 1 versus 0 and 2) matter in terms of whether I should run these on separate samples (0 and 1) versus (0 and 2) rather than jointly?

Thanks in advance.
