Hello everyone,

I am currently working on a project investigating the impact of political socialization under communism on citizens' regime support. Therefore, I conduct a fixed-effects regression (see code below) for which I would like to test whether I need robust standard errors. What is an appropriate test for that? Additionally, can I use the standard errors by simply typing "robust" behind the code? I am not sure about this because I read different things in this forum.

Code:
xtset country id // xtset macro-level micro-level 
xtreg regimesupport ib3.cohort income unemployment performance trust interest male i.education, fe robust
Any help is highly appreciate.
Kind regards,
Paula
