Thanks very much for providing me the way to fetch VCE. But, following
your
program, I got the error message r(2000), which says no observations.
I ran
the stata problem as follow:
use ":iMac:Users:james:Desktop:Thesis:I-Lung:fxdata.dta", clear
sort code
levels code, local(levels)
qui foreach l of local levels {
regress rtnstk rtnmkt rtndla dlayen rtnyen if code ==`l'
matrix cv`l' = get(VCE)
}
----------------------------------------------------------------
The details are
use ":iMac:Users:james:Desktop:Thesis:I-Lung:fxdata.dta", clear
. sort code
. levels code, local(levels)

>>> I guess that for at least one of your codes you
have insufficient observations. Missing values
on any of the variables would not help.
A work-around is to use -capture-
levels code, local(levels)
qui foreach l of local levels {
capture regress rtnstk rtnmkt rtndla dlayen rtnyen if code ==`l'
if _rc {
di "code `l': error" _rc
}
else matrix cv`l' = get(VCE)
}
There is more at [P] capture or in the references in my previous
post in this thread.
