Hello,

I am trying to run a regression using a panel data, using something like: "xtreg wages i.high_qual i.illness_disability i.reason_for_leaving_job if training==1 & education==1, re". However, despite that my dataset is large (around 300,000 observations), STATA gives out an error term saying "insufficient observations r(2001)". Does anyone know what the problem may be? I am not convinced that it is a lack of sufficient observations. Would be very grateful!!
