Dear all,
I'm trying to run DEA with a panel of 150 hospitals.
As an illustration, to get an idea of how it works, I tried the
example provided by Scott Merryman in this forum:
sysuse auto,clear
keep in 1/5
rename make dmu
dea length weight = mpg, saving(deaout)
use deaout,clear
tobit theta price, ul(1)
But immediately after the command: dea length weight = mpg, saving(deaout) :
I receive:
too few variables specified
Any idea what might be the reason?
I have installed all the files under findit dea
Thanks in advance,
