st: drop observations panel data
I have a panel data set with tradingpair as the ID and year as the time
variable. For some of the tradingpairs I would now like to drop observations
whenever year<1995. Hence, I would need a command like
drop if tradingpair=countryX and year<1995
I'm sure there is a straightforward solution to this, however, i haven't
been able to find one going through the manuals and earlier statalist
Any help is very much appreciated!
