PDL::NDBin - Multidimensional binning & histogramming 2 ++

In scientific (and other) applications, it is frequently necessary to classify a series of values in a number of bins. For instance, particles may be classified according to particle size in a number of bins of, say, 0.01 mm wide, yielding a histogra...

Math::Vector::Real - Real vector arithmetic in Perl 4 ++

A simple pure perl module to manipulate vectors of any dimension. The function "V", always exported by the module, allows one to create new vectors: my $v = V(0, 1, 3, -1); Vectors are represented as blessed array references. It is allowed to manipul...

Algorithm::KMeans - Clustering multi-dimensional data with a pure-Perl implementation ++

Algorithm::KMeans is a *perl5* module for the clustering of numerical data in multidimensional spaces. Since the module is entirely in Perl (in the sense that it is not a Perl wrapper around a C library that actually does the clustering), the code in...

Statistics::Multtest - Control false discovery rate in multiple test problem ++

For statistical test, p-value is the probability of false positives. While there are many hypothesis for testing simultaneously, the probability of getting at least one false positive would be large. Therefore the origin p-values should be adjusted t...
