Hi,

I have a panel with 19 regions over 25 years, and I want to generate a
variable equal to the mean of X in all regions except one. To be more
precise; all observations should equal the mean of X that year,
excluding the region corresponding to that cell.
Something like this: For observation "region 1, year 1": my variable
should equal the mean of X for year 1 for all regions but region 1.
For observation "region g, year t": my variable should equal the mean
of X for year t for all regions but region g.
The idea is to compare the value of an observation in a region with
the mean of the observations in all the other regions within the same
year.

Any suggestions?
