CarbocationStatisticsBundle
===========================

[](#carbocationstatisticsbundle)

This is a pure PHP library that implements multivariate linear regression using linear algebra. The Moore-Penrose pseudoinverse is used in the computation of the coefficient matrix. The original regression and matrix libraries were written by Shankar Manamalkav, and the original files can be found [on his blog](http://mnshankar.wordpress.com/2011/05/01/regression-analysis-with-php/). It has been adapted as a Symfony2 bundle by James Pirruccello.

This bundle is covered by the MIT license. For details, [see the license](https://github.com/carbocation/CarbocationStatisticsBundle/blob/master/Resources/meta/LICENSE).

Symfony2 Installation
---------------------

[](#symfony2-installation)

This bundle can be used as a standalone package for PHP 5.3+. It can also be used as a Symfony2 bundle. To do so, follow these instructions (for the 2.0.x branch):

1. Add this bundle to your `deps` file:

    ```
    [CarbocationRegressionBundle]
        git=git://github.com/carbocation/CarbocationStatisticsBundle.git
        target=/bundles/Carbocation/StatisticsBundle

    ```

    Then run `bin/vendors install`.
2. Register the `Carbocation` namespace in the `app/autoload.php` file:

    ```
    $loader->registerNamespaces(array(
        // ...
        'Carbocation'      => __DIR__.'/../vendor/bundles',
    ));

    ```
3. Register the bundle in the `app/AppKernel.php` file:

    ```
    public function registerBundles()
    {
        $bundles = array(
            // ...
            new Carbocation\StatisticsBundle\CarbocationStatisticsBundle(),
        );
    }

    ```
