Painel data

[Rodrigo Monteiro Barbosa]

Hi

I'm with a doubt when I do a painel data. The estimations of my B's in re and fe aren't different, I use the vce(robust) to correct my standard deviation, but I really don't know if this is a problem.

Thanks a lot for any help

welcome to this forum
As you may envisage it's virtually impossible to reply to your question helpfully with no clue of what you typed and what Stata gave you back.
Please, see the FAQ on CODE delimiters (just click on the A toggle, click on the # button and paste what you typed and what Stata gave you back in between).
You will obtain something similar to the following code:

. use "C:\Program Files (x86)\Stata15\ado\base\a\auto.dta"
(1978 Automobile Data)

. sum price

    Variable |        Obs        Mean    Std. Dev.       Min        Max
-------------+---------------------------------------------------------
       price |         74    6165.257    2949.496       3291      15906

As Carlo well pointed out, it is unfeasible to provide a precise reply under such an overarching topic, more so when details are lacking.

That being said, and assuming you have longitudinal data, the best approach tends to be the one using a panel data analysis. With regards to fe versus re, apart from - hausman - command, the background literature in your field as well as the purpose of the study can be taken as beacons to your route.
