README
The Next Value Predictor is a PHP package that predicts the next value based on the previous values for a given data set. It considers the previous values and calculates the probability of the next value. The package is intended for use in applications that require predictive analysis capabilities.
Installation
To use the package, run the following command in the command line:
$ composer require esplora/next-value-predictor
Usage
To use the package, instantiate the Predictor class, passing an array of previously recorded values as the parameter, and then call the predict() method to predict the next value.
use Esplora\Predictor\Predictor; $predictor = new Predictor([1, 3, 1, 4, 2, 4, 3, 1, 4, 1, 4, 2, 1, 4, 5]); $predictor->predict(); // 3.004
Weights are optional and enable you to set weighting parameters for different categories of data to help balance unbalanced sets.
To use weights, pass in the desired weight as an argument for predict().
$predictor = new Predictor([1, 3, 1, 4, 2, 4, 3, 1, 4, 1, 4, 2, 1, 4, 5]); $predictor->predict(0.0); // 5.0 $predictor->predict(0.5); // 1.789,
You can also use the probabilityGreaterThan() method to get the probability of the next value rate being greater than a certain number.
$predictor->probabilityGreaterThan(5); // 0.0 $predictor->probabilityGreaterThan(0); // 1.0
