I would like to run the regression where my dependent variable is "dep_var" which change by gid (it is a code from a grid cell 50x50km) and year. I want to regress dep_var on the interaction term between prec_gpcc (which change by gid and year) and Grid_fix (which change only by gid)
I think I have to control by year fixed effect and grid cell fixed effect. Hence, I am using command reg2hdfe with the following specification:
Code:
reg2hdfe nactors2 c.prec_gpcc##c.ELF_L5, id1(year) id2(gid)
Best,
Diego.
