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 trialanderror 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.
