Thanks Maarten, I have a brief follow-up question you'll see at the end of the paragraph. I certainly would refere to XT manual on xtmixed. Looks like you I need laymans manual. Can you give me a laymans explanation to estimations such as differencing 1997 and 2001. especially, some tips on commands and some intution.Thanks very much again. this will help. See belowhow my data is..I have 47 reporters, 65 partner countries, but also also broken down at sector level.


LnVSikj = Ai+ 1LnTarOik + 2LnTarPikj + 3LnICTikj + 4LnInfrOijk+ 5LnInfPijk

+ 6LnResik + 7LnCapik + 8LnPolik +9LnFinik +10LnGDPik + 11LnRemotijk (4) + Uijk




Nihal Pitigala:
If the data is set up as in the example you show, than you are ready to go:
just type -reg LnTrade LnTariff LnTransports- (without the hyphens). You
might want to consider moving into crossed random effects here using
-xtmixed-, since each pair of countries is nested within its constituent
countries plus each pair consists of multiple entries, which are again nested
within sector. The entry for -xtmixed- in the XT manual is good in explaining
how to set that model up.
HTH,
Maarten
