Usage

Linear Regression

In simple linear regression, we predict scores on one variable from the scores on a second variable. The variable we are
predicting is called the criterion variable and is referred to as Y. The variable we are basing our predictions on is
called the predictor variable and is referred to as X.

use TeamTNT\PlayFair\Math\Statistics\LinearRegression;

$x = [1,2,3,4,5];
$y = [1,2,1.3,3.75,2.25];

$lr = new LinearRegression;
$rez = $lr->calculate($x, $y);

$slope = $rez[0];
$intercept = $rez[1];
