hello,

I have a dataset on which I want to perform an OLS. The dataset looks like this:
dependent variable: percentage change of carbon emission of each firm between 2013 and 2018
dependent variables: mean of various firm characteristics from 2010 to 2012.

However, note that I started from a panel dataset to construct this sample, but in my final sample i have only one observation per firm per variable. Am I still able to perform xtreg? Because whenever I try to do this, all my variables are omitted automatically.

Kind regards,
Timea De Wispelaere
