I have hundred lines of arrays of data. Each array is a sampled representation of a distribution.

I want to calculate standard deviation and mean for data array, then use the standard deviation and mean to perform cluster analysis. The aim is to group similar arrays in to one cluster.

What is a good perl module to do this job? Or you know there are better and faster method to get job done instead calculate mean and standard deviation, please give me some hints.

    Eily thinks vrk is a cookie monster
    talexb thinks the term 'cookie monster' is unnecessarily drogatory ;) and takes a cookie as well. Mmmm. Delicious cookies.
