Thank you very much for your response, Roger. I'm studying these pdf files that you recommended.

My intention is to compare 4 distributions to each other. My concern, then, is on how to do it with only one application of a test, if possible. If not, which tests would be available?

best,
alvaro

Dear colleagues,
I have four lists of efficiency scores, which allow to order several
individuals according to their performance in different sectors.
I need to test if these rank-distributions are similar.

I wonder, is there any test that would help me to do this in just one
test ?
Alvaro has not specified which rank distributions are to be compared with
which other rank distributions, or what question exactly is being asked.
However, the -somersd- package, downloadable from SSC, produces
confidence limits for a wide range of rank statistics, and probably can
do whatever Alvaro actually wants to do. It comes with a .pdf manual
which explains the principles behind these statistics.

I hope this helps.

Roger
