# Statistics
[](https://github.com/msharp/elixir-statistics/actions/workflows/elixir.yml)
[](https://hex.pm/packages/statistics)
Statistics functions and distributions for [Elixir](https://github.com/elixir-lang/elixir).
## Usage
Add Statistics as a dependency in your `mix.exs` file to install from [hex.pm](https://hex.pm).
```elixir
def deps do
[
{ :statistics, "~> 0.6"}
]
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)
2.5998185179627384
```
## Documentation
Elixir has great documentation tools using `ex_doc`.
The docs are hosted on [hexdocs.pm/statistics](http://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.
