#  Statistics

[![Build Status](](
[![ version](](

Statistics functions and distributions for [Elixir](

## Usage

Add Statistics as a dependency in your `mix.exs` file to install from [](

def deps do
    { :statistics, "~> 0.6"}

After you are done, run `mix deps.get` in your shell to fetch and compile Statistics.

To try it out, start an interactive Elixir shell with `iex -S mix`.

Get the median value from a list

iex> Statistics.median([1,2,3])

Calculate the variance of a list of values.

iex> Statistics.variance([1,2,3,4])

Or draw a random number from a Gaussian distribution with a mean of 1 and standard deviation of 2.

iex> Statistics.Distributions.Normal.rand(1, 2)

## Documentation

Elixir has great documentation tools using `ex_doc`.

The docs are hosted on [](

## Performance

This is not a library to use if you need fast computation.

Everything is implemented in Elixir. Many of the implementations use slow approximations, numerical function integration, or trial-and-error methods.

There is much room for improvement. To make this library really fast (and precise), we would probably need to interface with existing C libraries.
