Re: st: Re: Running a foreach loop over a sequence of dates
BTW, Augusto did not even pretend that his was a -numlist-; if he had
thought it was one, he would have said something like "...of numlist
blabla". His example looks like "any_list" in the -h foreach- parlance. He
could of course use a loop beforehand to fill a -local- with the desired end
dates and use that in the -foreach- ...

Ah, so true -- but by labeling it as "pseudo-code", Augusto indicated
that he already knew that. Nonetheless, looping over dates would be
*extremely* high on my list of wishes & grumbles! Perhaps in Stata
11.... or even 10.2. (Since, in the end, dates are just formatted
numbers, this seems as if it should be possible in theory.) There are
applications in which something much more light-weight than - rolling-
would be appropriate. Although I agree that the example below could
likely be accomplished with -rolling-.

You cannot simply abbreviate your list of end dates like a - numlist-
with a slash and hope for Stata`s acquiescence... I would recommend you
look at -h rolling-

Subject: st: Running a foreach loop over a sequence of dates
Hello,
I am trying to run a series of commands in a time series setting, and
interested in using variable time intervals (variable time windows, or
variable start/end dates). So ideally, I would like to loop with
-foreach- over a series of dates, but I cannot find the way of doing
this. To give you an idea of the kind of problem, here it is in
pseudo-code (not working):
*** begin pseudo-code
foreach t in 1992q1/2000q4 {
reg y L.y L.x if tin(1960q1, `t')
reg y L.y L.x if tin(`=`t'-20', `t')
}
*** end pseudo-code
I am sorry if this is a trivial question, but I really could not find
a way of performing this. Thanks for any hints.
AC
