lobf

Find the line of best fit given a set of points

Example Usage

const lobf = require('lobf');
 
const myLineOfBestFit = lobf([
    // [x, y]
    [1.5, 3],
    [1.5, 2],
    [2, 1.5]
]);
 
console.log(myLineOfBestFit);
// Logs {
//	'slope' : -2,
//	'intercept' : 5.5
// }

API

module.exports is a function as follows:

• function (points: [x, y][]) - calculate the line of best fit for the given points.
  • points: [x, y][] - an array of arrays with element 0 as the x coordinate and element 1 as the y coordinate.
  • returns - { slope, intercept }:
    • slope: Number - the slope of the line, or the m in y = mx + b.
    • intercept: Number - the intercept of the line, or the b in y = mx + b.
