Math::GSL::Statistics - Statistical functions
use Math::GSL::Statistics qw /:all/;
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 $data.
For samples drawn from a gaussian distribution the variance of \Hat\mu is \sigma^2 / N.gsl_stats_variance($data,
$stride,
$n)gsl_stats_sd gsl_stats_sd_m gsl_stats_variance_with_fixed_mean gsl_stats_sd_with_fixed_mean gsl_stats_tss gsl_stats_tss_m gsl_stats_absdev gsl_stats_skew gsl_stats_kurtosis gsl_stats_lag1_autocorrelation gsl_stats_covariance gsl_stats_correlation gsl_stats_variance_m($data,
$stride,
$n,
$mean)gsl_stats_absdev_m gsl_stats_skew_m_sd gsl_stats_kurtosis_m_sd gsl_stats_lag1_autocorrelation_m gsl_stats_covariance_m gsl_stats_wmean gsl_stats_wvariance gsl_stats_wsd gsl_stats_wvariance_with_fixed_mean gsl_stats_wsd_with_fixed_mean gsl_stats_wtss gsl_stats_wtss_m gsl_stats_wabsdev gsl_stats_wskew gsl_stats_wkurtosis gsl_stats_wvariance_m gsl_stats_wsd_m gsl_stats_wabsdev_m gsl_stats_wskew_m_sd gsl_stats_wkurtosis_m_sd gsl_stats_pvariance gsl_stats_ttest gsl_stats_max gsl_stats_min gsl_stats_minmax gsl_stats_max_index gsl_stats_min_index gsl_stats_minmax_index gsl_stats_median_from_sorted_data gsl_stats_quantile_from_sorted_data The following function are simply variants for int and char of the last functions:

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 :
