CorrelationCalculatorBundle
===========================

[](#correlationcalculatorbundle)

This bundle provides simple implementation of [Pearson product-moment correlation coefficient calculator](https://en.wikipedia.org/wiki/Pearson_product-moment_correlation_coefficient).

It can be used to calculate correlation coefficient between two samples of data (X and Y).

The resulting correlation coefficient ranges from −1 to 1. A value of 1 implies that a linear equation describes the relationship between X and Y perfectly, with all data points lying on a line for which Y increases as X increases. A value of −1 implies that all data points lie on a line for which Y decreases as X increases. A value of 0 implies that there is no linear correlation between the variables.

Installation
------------

[](#installation)

`composer require addvilz/correlation_calculator_bundle`

Sample usage
------------

[](#sample-usage)

### Symfony2 service

[](#symfony2-service)

Bundle exposes service `addvilz_correlation_calculator.correlation_calculator`, an instance of `CorrelationCalculator`.

You can use it like this:

```
    services:
        myvendor.bundle.some_class:
            class: MyClass
            arguments:
                @addvilz_correlation_calculator.correlation_calculator

```

```
    class MyClass
    {
        private $correlationCalculator;

        function __construct(CorrelactionCalculator $correlationCalculator)
        {
            $this->correlationCalculator = $correlationCalculator;
        }

        function doStuff(array $x, array $y)
        {
            $this->correlationCalculator->calculateCoefficient(new SampleCollection($x, $y));
        }
    }

```
