absorbing more than two variables in a regression

[Paula de Souza Leao Spinola]

Hello
Would anyone know how to absorb more than two factor variables in a regression?
I tried as below but it did not work

. areg d_pc i.diasem##i.turno i.anomes, absorb(mun_res codestab) cluster(mun_res codestab)
absorb():  too many variables specified
r(103);

Hi.
There are two user written commands you can use for that. You have -reghdfe- and -regxfe-. You should be able to find them online from the Stata command line.
