Although one can never be sure what's in someone else's mind, Isuspect you are looking for cluster analysis. -help cluster- . Finitemixture models may also be of interest. -findit fmm- .

I want to separate the packets into groups so that the group members are most similar to one another. I am looking for a method (or methods?) to achieve this end but I don't know where to start. If you can think of any suggestion please fire away and I'd be most grateful! Regards, Ada
