Simple Linear Regression.

Installation

$ npm install --save ml-regression-simple-linear

Usage

import SimpleLinearRegression from 'ml-regression-simple-linear';

const x = [0.5, 1, 1.5, 2, 2.5];
const y = [0, 1, 2, 3, 4];

const regression = new SimpleLinearRegression(x, y);

regression.slope // 2
regression.intercept // -1
regression.coefficients // [-1, 2]

regression.predict(3); // 5
regression.computeX(3.5); // 2.25

regression.toString(); // 'f(x) = 2 * x - 1'

regression.score(x, y);
// { r: 1, r2: 1, chi2: 0, rmsd: 0 }

const json = regression.toJSON();
// { name: 'simpleLinearRegression', slope: 2, intercept: -1 }
const loaded = SimpleLinearRegression.load(json);
loaded.predict(5) // 9
