NAME

Statistics - Raku module for doing statistics

SYNOPSIS

use Statistics;

my @test1 = [6,6,4,6,8,6,8,4,4,6,6,8,8,8,8,8,8,4,4,4,4,8,8,8,8,4,4,4,8,6,8,4];
my @test2 = [160.0,160.0,108.0,258.0,360.0,225.0,360.0,146.7,140.8,167.6,167.6,

DESCRIPTION

Statistics is a module to make it easier to do statistics in Raku programming language.

Many things are in the roadmap, only few are done.

NOTE

Because of absence of easy to use matrix library like numpy in Raku, implementing many of the tests is very difficult. Whatever can be done with Python statistics module will all be implemented.
