Statistics::Descriptive - Module of basic descriptive statistical functions.
use Statistics::Descriptive;
my $stat = Statistics::Descriptive::Full->new();
$stat->add_data(1,2,3,4);
my $mean = $stat->mean();
my $var = $stat->variance();
my $tm = $stat->trimmed_mean(.25);
$Statistics::Descriptive::Tolerance = 1e-10;
This module provides basic functions used in descriptive statistics. It has an object oriented design and supports two different types of data storage and calculation objects: sparse and full. With the sparse method, none of the data is stored and only a few statistical measures are available. Using the full method, the entire data set is retained and additional functions are available.
