[![Build Status](https://camo.githubusercontent.com/029790d58b68e15c0e29d402de8bb94cebc8eb7ad2b77f27c76acdc27c5747c0/68747470733a2f2f7472617669732d63692e6f72672f6d61686572696f2f70687073746174732e737667)](https://travis-ci.org/maherio/phpstats)

A php library containing useful advanced statistic modeling. Helps replace the unsupported PECL stats extension.

What's included?
----------------

[](#whats-included)

There are currently helper methods to do the following:

- Generating random Gaussian, Gamma, and Beta variates
- Calculating the mean and variance of a data set

Usage
-----

[](#usage)

To use this library, just install via composer:

```
composer require maherio/phpstats

```

The functions are now globally accessible. Here are a couple examples:

Generate a random beta variate:

```
$a = 10;
$b = 1500;
$beta_variate = generate_random_beta_variate($a, $b);

```

Calculate the variance of a data set:

```
$data_set = [1,3,5,1,6,15,2,1];
$variance = calculate_variance($data_set);

```
