README
Statistics
Statistics functions and distributions for Elixir.
Usage
Add Statistics as a dependency in your mix.exs file to install from hex.pm.
def deps do
[
{ :statistics, "~> 0.6.2"}
]
end
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])
2
Calculate the variance of a list of values.
iex> Statistics.variance([1,2,3,4])
1.25
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 hexdocs.pm/statistics.
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.
