Re: st: tsset - repeated time values within panel

[emanuele mazzini <madsoenistata@gmail.com>]

Hi Nick.
Thank you very much for your suggestion. The command you gave me did
work, but how can I replace now missing values for some given years
for which I have data for the previous/following years? I tried the
command: replace myvar = L.myvar if myvar >=. but it does not work.

Thank you very much in advance,
Emanuele.
