Hello, I am estimating a first difference model of this kind: d.y= d.x1 + d.x2 + d_t*. where x1 and x2 are my covariates and d_t* are the differenced time dummy for time fixed effects. I would like to estimate the model using Driscoll-Kraay standard errors.
Currently I am using the following command:

Code:
xi: xtscc d_y d_x2 d_x2 d_t*
where d_ indicates variables that I have previously differenced.

The problem with this estimation is that xtscc reports the constant term, that I would like to exclude in a differenced model. Does anyone know how can I remove the constant from my estimation?

thank you very much in advance for your help

best regards
