M Carney:
Assuming var1 is your stock return date variable, and var2 is the dummy
variable you want:
gen byte m=month(var1)
gen byte d=day(var1)
gen var2=0
replace var2=1 if m==1 & (d>=1 & d<=10)
I think that should work. More help can be found in the Stata User's
Guide.
Regards,
Alex

Subject: st: data extraction by date
I have a series of stock returns sorted by Stata's standard date form
(that is, when 0 = 1Jan 1960). Is it possible for me to create a data
set with 1 for all dates ranging from 1 jan to 10 jan (including all
years) and zero otherwise. I've tried
. gen var2 = var1 if doy(1/4), month(1)
but it doesn't seem to work. Any help would be appreciated immensely!!!
regards,
Mike
