Hi,

I am trying to estimate the impact of directors' remuneration on firm performance. My unbalanced data set comprises 1696 firms and 16 time periods (in particular, years). I have 7 independent variables in total. I am trying to run a Fama-MacBeth regression using the 'asreg' routine. Following is the command for the same:


Code:
asreg Profitability4 Size2  Leverage1 CurrentRatio SalesGro CapitalExpenditure2 WPromoterSharesin1 NonIndependent_Totalremunerati, fmb newey(2)
However, I get the following error:

Code:
. asreg Profitability4 Size2 Leverage1 CurrentRatio SalesGro CapitalExpenditure2 WPromote
> rSharesin1 NonIndependent_Totalremunerati, fmb newey(2)
_b_NonIndependent_Totalremunerati invalid varname
r(198);
I would like to clarify that the variable name (NonIndependent_Totalremunerati) seems to be correct because this issue is only occurring in the 'asreg' routine and not in other routines such as xtreg and regress.
