Regression variable dummy

[Daffa Ibrahim]

I would like to investigate the effects of economic growth, population growth and inequality on CO2 emissions during the SDGs with panel data regression. I used a dummy variable on the SDGs variable (0=years before SDGs and 1=years after SDGs). And my regression syntax is
reg emico2 gdp pop ineq dm i.code
Is that true?
I am very layman about STATA

Daffa:
welcome to this forum.
If you are dealing with a panel dataset with a continuous regerssand, you should start from -xtreg- with the -fe- or the -re- specification.
Pooled -regress. is an option if you detect no evidence of a panel-wise effect.
See -xtreg- entry in Stata .pdf manual for further details.

Thanks for the response, sir
I appreciate that, it means a lot to me
I have written xtset code year
The best method (FEM) has also been selected.
what syntax should I write for my dummy variables (SDGs)?

I would go:

xtreg reg emico2 gdp pop ineq dm i.SDGS, fe vce(cluster idcode)
