```

# bh-regression

The bh-regression module allows to compute linear regression.

# Usage example:

```js
const BHRegression = require('bh-regression');

var data = [
  [1, 0],
  [2, 100],
  [3, 30],
  [4, 0],
  [5, 60],
  [6, 20],
  [7, 40],
  [8, 100],
  [9, 20]
];
var result = BHRegression.linear(data);

/**
 * result.a: coefficient from f(x) = a * x + b.
 * result.b: value from f(x) = a * x + b.
 * result.line: regression line data [[x, y], ...].
 * result.lessSquare: less square coefficient.
 * result.percent: less square coefficicient * 100
 */
