<a name="5.0.0"></a>

5.0.0 (2017-09-26)

Features

• Expose ES6 modules (a775ef6), closes #210
• kernel density estimation (#245) (8637af1), closes #244

BREAKING CHANGES

• simple-statistics now uses ES6 modules internally, and exposes a entry point for other modules to use it as an ES6 module.

This means:

• If you use Rollup or another library that supports the jsnext:main or module fields of package.json, you'll likely automatically start using this feature. When you use simple-statistics as an ES6 module, import {min} from "simple-statistics" and other imports of only a few of its methods will automatically do 'tree-shaking' and only pull in the parts you use (if your bundling tool supports tree-shaking)
• Sub-requiring parts of simple-statistics, like require('simple-statistics/min') is deprecated and will not work. Its components are now written with ES6 syntax.

4.1.1 (2017-08-05)

Bug Fixes

• expose BayesianClassifier & PerceptronModel instead of bayesian and perceptron (1d03671)

4.1.0 (2017-04-27)

Features

• sampleKurtosis (1d9eec2)

<a name="4.0.0"></a>

4.0.0 (2017-04-25)

Bug Fixes

• Remove mixin method (#215) (85036e2), closes #211

Performance Improvements

• binomialDistribution: avoid expensive factorial calculations (#205) (525f9c0)
• core: Improve performance of min, max, sumNthPowerDeviations, variance, sampleVariance (#195) (9d2569a)
• distributions: return array instead of object (#209) (6c5df5f)
• poissonDistribution: avoid expensive factorial calculation (#206) (b34aceb)
• poissonDistribution: use Math.exp instead of Math.pow (#208) (6491dfa)
• sampleSkewness: Improve sampleSkewness performance (#197) (03d37eb)
• sum: Switch from Kahan to Kahan-Babuska algorithm (1b42d7f)

BREAKING CHANGES

• Removes .mixin(). Instead use simple-statistics in a functional style.
• distributions: The return value of bernoulliDistribution, binomialDistribution, and poissonDistribution is no longer an Object with number keys, it is now an Array of numbers.

<a name="3.0.0"></a>

3.0.0 (2017-04-06)

Breaking change: before this release, simple-statistics would return NaN when provided with invalid input. After 3.0.0, simple-statistics will throw exceptions when provided with invalid input. If you previously used isNaN to test for these error cases, switch to using try and catch, or make sure that valid input is given to simple-statistics.

Features

• mean: combineMeans, a method for combining calculated means (d9e3ebc)
• mean: subtractFromMean, a method to remove a value from the mean (afe76e9)
• variance: combineVariances, a method for combining pre-calculated variances of two dataset (68133f7)

<a name="2.5.0"></a>

2.5.0 (2017-02-24)

Features

• mean: addToMean, a method to update an mean with a new element (b6637b4)

<a name="2.4.0"></a>
