NAME

Math::GSL::Statistics - Statistical functions

SYNOPSIS

use Math::GSL::Statistics qw /:all/;

DESCRIPTION

Here is a list of all the functions in this module :

  • gsl_stats_mean($data, $stride, $n) - This function returns the arithmetic mean of the array reference $data, a dataset of length $n with stride $stride. The arithmetic mean, or sample mean, is denoted by \Hat\mu and defined as, \Hat\mu = (1/N) \sum x_i where x_i are the elements of the dataset $data. For samples drawn from a gaussian distribution the variance of \Hat\mu is \sigma^2 / N.

You have to add the functions you want to use inside the qw /put_funtion_here /. You can also write use Math::GSL::Randist qw/:all/; to use all avaible functions of the module. Other tags are also avaible, here is a complete list of all tags for this module :

all
int
char

For more informations on the functions, we refer you to the GSL offcial documentation: http://www.gnu.org/software/gsl/manual/html_node/

Tip : search on google: site:http://www.gnu.org/software/gsl/manual/html_node/ name_of_the_function_you_want
