All,
Quick Q about -weights-.
In running -xtregar- models, I want to include a weight = (1/prob), where
prob denotes the probability of _i_ being selected for inclusion in each
region.
. sum weight
Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
weight | 3457 .9997022 .0421402 .914787 1.092308
The Ns are grouped in panels of 6.
Now -pweight- is the natural candidate for use here, but since all -xt-
commands disallow the use of -[pw=...]- and -[iw=...]- and will not allow
-[fw=...]- since my weight includes noninteger values, could anybody on
the list tell me whether it is sensible to use -[aw=...]- purely on a
'last man standing' basis?
