PDL-Stats This is a collection of statistics modules in Perl Data Language, with a quick-start guide for non-PDL people. They make perldl--the simple shell for PDL--work like a teenie weenie R, but with PDL threading--"the fast (and automagic) vectorised iteration of 'elementary operations' over arbitrary slices of multidimensional data"--on procedures including t-test, ordinary least squares regression, and kmeans. Of course, they also work in perl scripts. VERSION 0.2.1 DEPENDENCIES PDL Perl Data Language. Preferably installed with a Fortran compiler. A few methods (logistic regression and all plotting methods) will only work with a Fortran compiler and some methods (ordinary least squares regression and pca) work much faster with a Fortran compiler. GSL GNU Scientific Library. This is required by PDL::Stats::Distr and PDL::GSL::CDF, and provides p-values for PDL::Stats::GLM. INSTALLATION To install all included modules, run the following commands in the current dir: perl Makefile.PL make make test make install SUPPORT AND DOCUMENTATION After installing, you can find documentation for the modules with the perldoc command. perldoc PDL::Stats perldoc PDL::Stats::Basic perldoc PDL::Stats::Distr perldoc PDL::Stats::GLM perldoc PDL::Stats::Kmeans perldoc PDL::GSL::CDF You can also look for information at: Search CPAN http://search.cpan.org/dist/PDL-Stats/ Sourceforge http://pdl-stats.sourceforge.net COPYRIGHT AND LICENCE ~~~~~~~~~~~~ ~~~~~ ~~~~~~~~ ~~~~~ ~~~ `` ><((("> Copyright (C) 2009 Maggie J.
