Returns the improvement rate of your AB-test (```challengerImprovement```) and answers if it's statistically significant (```isSignificant```).

The result returned also contains a ```statistics``` property with calculated statistical values.

	npm install --save ab-test-result

## Usage

```javascript

	var abTestResult = require('ab-test-result');

	var test = {

		controlVisits: 490, // required

		controlConversions: 10, // required

		challengerVisits: 500, // required

		challengerConversions: 17 // required

	};

	var confidence = 0.9; // optional, defaults to 0.95

	var result = abTestResult.calcResult(test, confidence);

	/*

		result = {

			controlConversionRate: 0.02040816326530612,

			challengerConversionRate: 0.034,

			challengerImprovement: 0.666,

			isSignificant: true,

			statistics: {

				controlStandardError: 0.006387435072946544,
