Good Day Everyone!

I am doing a panel regression on have a problem in running panel models in Stata. I wanted to know which panel model should I use for my data by testing Fixed Effects, Random Effects, and Pooled OLS.

The first steps I did is to import the excel containing the data, [xtset COMPANY YEAR], [regress DummyVariable IndependentVariables], and vif (which resulted to 1.26).

Then the problem happens whenever I run xtreg DummyVariable IndependentVariables, fe or xtreg DummyVariable IndependentVariables, re. This command results to periods on the models and it omits all variables. What should I do from here?
