[![Build Status](https://camo.githubusercontent.com/40dc1bb0b0020912314556eb2a55f17b670fb9ddfb76bbfb38db3674583f3443/68747470733a2f2f7472617669732d63692e6f72672f6d6167617261732f7073746174732e7376673f6272616e63683d6d6173746572)](https://travis-ci.org/magaras/pstats)

A PHP library containing a lot of statistical methods, from the most usefull ones (*like mean and variance*) to even some more sophisticated, like moving average and outliers around median.

I intend to keep updating this library in order for it to be as thorough as possible.

Install with composer `composer require magaras/pstats`.

The library supports the following methods:
===========================================

[](#the-library-supports-the-following-methods)

**Mean**

```
Basic::mean($data);
```

\*\* Median\*\*

```
Basic::median($data);
```

**Mode**

```
Basic::mode($data);
```

**Range**

```
Basic::range($data);
```

**Percentage Change**

```
Basic::percentageChange($start_value, $end_value);
```

**Percentage Difference**

```
Basic::percentageDifference($start_value, $end_value);
```

**Absolute Error**

```
Error::absoluteError(0, 0);
```

**Mean Absolute Error**

```
Error::mae($actuals, $predictions);
```

**Mean Square Error**

```
Error::mse($actuals, $predictions);
```

**Variance *(population / sample)***

```
Error::variance($data, true);
Error::variance($data, false);
```

**Std**

```
Error::std($data);
```

**Absolute / Relative / Cumulative Frequency for continuous values**

```
$frequency_classes = Frequency::frequencyContinuous($data);

$frequency_classes[$i]->absolute_frequency

$frequency_classes[$i]->relative_frequency

$frequency_classes[$i]->cumulative_frequency
```

**Absolute / Relative / Cumulative Frequency for discrete values**

```
$frequency_classes = Frequency::frequencyDiscrete($data);

$frequency_classes[$i]->absolute_frequency

$frequency_classes[$i]->relative_frequency

$frequency_classes[$i]->cumulative_frequency
```

**Simple Moving Average**

```
MovingAverage::simpleMovingAverage($moving_average_value, $data);
```

**Exponential Moving Average**

```
MovingAverage::exponentialMovingAverage(moving_average_value, $data);
```

**Outliers Around Mean**

```
Outliers::outlierAroundMean($data);
```

**Outliers Around Median**

```
Outliers::outlierAroundMedian($data);
```
