When I run:

Code:
resetxt esg totmktval, id(id) it(date) model(xtbe)
I get:
Code:
============================================================================== 
 * Between-Effects Panel Data Regression
and then Stata locks up, I terminated it after ten minutes. I've also tried xtfe as specification. My data set is not that large and other regressions/commands finish instantly. My panel data is set up using:

Code:
xtset id date
Any idea how I should approach/investigate this in order to find a solution?
