Description
-----------

[](#description)

- Implementation of model building for regression
- New models of regression in the development
- There will be a separate thread for php 5.6

Requirements
------------

[](#requirements)

- composer dependency (Carbon DateTime, random-bytes)
- > = PHP 7.0

Install
-------

[](#install)

```
composer require robotomize/regression-php
```

### Linear regression algorithm

[](#linear-regression-algorithm)

Basic usage

```
$testData = [[0, 10], [1, 20], [2, 3], [3, 15], [4, 0]]
$linear = new LinearRegression();
$linear->setSourceSequence($testData);
$linear->calculate();

/** @var RegressionModel $regressionModel */
$regressionModel = $linear->getRegressionModel();
```

Factory usage

```
/** @var RegressionModel $regressionModel */
$regressionModel = Regression::Linear([[0, 10], [1, 20], [2, 3], [3, 15], [4, 0]]);
```

### Exponential regression

[](#exponential-regression)

Basic usage

```
$exponential = new ExponentialRegression();
$exponential->setSourceSequence($testData);
$exponential->calculate();
$regressionModel = $exponential->getRegressionModel();
```

Factory usage

```
$regressionModel = Regression::Exponential($testData);
```

### Logarithmic regression

[](#logarithmic-regression)

### Basic usage

[](#basic-usage)

```
$logarithmic = new LogarithmicRegression();
$logarithmic->setSourceSequence($testData);
$logarithmic->calculate();

/** @var RegressionModel $regressionModel */
$regressionModel = $logarithmic->getRegressionModel();
```

### Factory usage

[](#factory-usage)

```
$regressionModel = RegressionFactory::Logarithmic($testData);
```

### Power regression

[](#power-regression)

### Basic usage

[](#basic-usage-1)

```
$powerReg = new PowerRegression();
$powerReg->setSourceSequence($testData);
$powerReg->calculate();

/** @var RegressionModel $regressionModel */
$regressionModel = $powerReg->getRegressionModel();
```

### Factory usage

[](#factory-usage-1)

```
$regressionModel = RegressionFactory::Power($testData);
```
