Hello,
My question is specific to -vecrank, but also more general to time series. When
I try to run this -bys countrycode, I often receive reports that there are gaps
in the sample (of course this message applies to a specific -countrycode).
After a little investigating, the gap is announced if there is data missing in
the series. So, if a country didn't report something for one period out of
many, I am unable to run these -vecrank or -johans or any other number.
Is there any way out of this? I am hesitant to -ipolate because there are cases
where more than just one data point is missing for a -countrycode. What other
options might there be?
Thanks,
Justin
