Dear Stata listers
I need to construct a number of summary statistics for clustered data
with a particular twist: for each observation the summary statistics
should be constructed without taking into the account the reference
observation.
I have a data base that has the following form:
id cluster X
1 1 0.5
2 1 0.7
3 1 0.4
. . .
. . .
. . .
100 3 0.6
101 3 0.6
102 3 0.8
103 3 0.2
that is observations can be grouped in clusters (of different size). I
am interested in constructing different statistics: for example for each
observation "i" I need to capture the average and standard deviation of
all observations that belong to the same cluster where "i" belongs
excluding observation "i".
Can somebody help me with a simple way of constructing this aggregates?
I appreciate the response
Javier
