Is there a CPAN module for creating the CDF for a given list?

It's not too difficult to implement, but it seems like Cumulative distri开发者_运维知识库bution function is a very basic Statistics::Descriptive function, doesn't it?

It seems Statistics::Descriptive::Weighted has it, but using Weighted (with equal points to all data...) instead of the simpler Statistics::Descriptive seems to have a large overhead.

There is Statistics::KernelEstimation. I have not used it but it looks OK.

Using Statistics::Descriptive::Weighted, you can omit the weights and each point will be assigned a unit weight by default.

A CPAN search came up with this: PDL::GSL::CDF. Its part of the PDL, the Perl Data Language (though this CDF module makes use of the GNU Scientific Library).
