A bundle to calculate distributions and some statistical important values with those distributions.

The API
-------

[](#the-api)

This bundle has three services that helps you with your distribution. Each service and function has comments that describes how to use them and why. This is a brief overview.

### Calculator

[](#calculator)

Use this service when you want to calculate a normal distribution. This service has two functions `normalDistribution`and `standardDistribution`. The later calculates the unit normal distribution where `meanValue = 0`and the `standardDistribution = 1`.

The input to both functions is an array with values like array(3,6,2,6,4,2,3,6,8, ... );

### DistributionManager

[](#distributionmanager)

This service builds a distribution of any type and saves some data in the database. The public functions to this service are `addDistribution`, `getPercentile` and `createValueFrequencyArray`.

`DistributionManager::addDistribution` takes an identifier name and an array with the values and frequency as arguments. The array must be on the form ($value => $frequency). See example below.
