Dear All,
I am trying to estimate non-linear trend of  variable industry over
the years  in a  within effect- panel regression but cannot find any
code which will achieve this . Could anybody please help?
The estimation is of the following form :
xi: xtreg $y $x1 if (indusid <50 & d_pvt==1 ),fe cluster(indusid)
global  y "lwages"
global x1    "tax_Esop_Ins linc i.indusid|year i.year i.state|year"
I would appreciate if anybody can help.
Thanks
Mukta
