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,

// }

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.
