Package Exports
- ml-regression
- ml-regression/lib/index.js
- ml-regression/src/index.js
This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (ml-regression) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation
$ npm install ml-regression
Examples
Simple linear regression
const SLR = require("ml-regression").SLR;
let inputs = [80, 60, 10, 20, 30];
let outputs = [20, 40, 30, 50, 60];
let regression = new SLR(inputs, outputs);
regression.toString(3) === "f(x) = - 0.265 * x + 50.6";External links

Polynomial regression
const PolynomialRegression = require("ml-regression").PolynomialRegression;
const x = [50, 50, 50, 70, 70, 70, 80, 80, 80, 90, 90, 90, 100, 100, 100];
const y = [
3.3, 2.8, 2.9, 2.3, 2.6, 2.1, 2.5, 2.9, 2.4, 3.0, 3.1, 2.8, 3.3, 3.5, 3.0,
];
const degree = 5; // setup the maximum degree of the polynomial
const regression = new PolynomialRegression(x, y, degree);
console.log(regression.predict(80)); // Apply the model to some x value. Prints 2.6.
console.log(regression.coefficients); // Prints the coefficients in increasing order of power (from 0 to degree).
console.log(regression.toString(3)); // Prints a human-readable version of the function.
console.log(regression.toLaTeX());
