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.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
Want more info? How to link or How to display code and escape characters are good places to start.
