|
### Bug Fixes
|
|
|
|
* Add index.js to package.json ([b744bfa](https://github.com/simple-statistics/simple-statistics/commit/b744bfa)), closes [#253](https://github.com/simple-statistics/simple-statistics/issues/253)

# [5.0.0](https://github.com/simple-statistics/simple-statistics/compare/v4.1.1...v5.0.0) (2017-09-26)
|
|
|
|
|
|
### Features
|
|
|
|
* Expose ES6 modules ([a775ef6](https://github.com/simple-statistics/simple-statistics/commit/a775ef6)), closes [#210](https://github.com/simple-statistics/simple-statistics/issues/210)
|
|
* kernel density estimation ([#245](https://github.com/simple-statistics/simple-statistics/issues/245)) ([8637af1](https://github.com/simple-statistics/simple-statistics/commit/8637af1)), closes [#244](https://github.com/simple-statistics/simple-statistics/issues/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.

|
|
* **distributions:** return array instead of object ([#209](https://github.com/simple-statistics/simple-statistics/issues/209)) ([6c5df5f](https://github.com/simple-statistics/simple-statistics/commit/6c5df5f))
|
|
* **poissonDistribution:** avoid expensive factorial calculation ([#206](https://github.com/simple-statistics/simple-statistics/issues/206)) ([b34aceb](https://github.com/simple-statistics/simple-statistics/commit/b34aceb))
|
|
* **poissonDistribution:** use Math.exp instead of Math.pow ([#208](https://github.com/simple-statistics/simple-statistics/issues/208)) ([6491dfa](https://github.com/simple-statistics/simple-statistics/commit/6491dfa))
|
|
* **sampleSkewness:** Improve sampleSkewness performance ([#197](https://github.com/simple-statistics/simple-statistics/issues/197)) ([03d37eb](https://github.com/simple-statistics/simple-statistics/commit/03d37eb))

|
|
### 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.

|
|
# [3.0.0](https://github.com/simple-statistics/simple-statistics/compare/v2.5.0...v3.0.0) (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.
|
|
|

# CHANGELOG
|
|
|
|
## 2.2.0
|
|
|
|
* Improved [Ckmeans](https://github.com/simple-statistics/simple-statistics/pull/163) algorithm
|
|
from the [updated R project](https://cran.r-project.org/web/packages/Ckmeans.1d.dp/NEWS)
|
|
that dramatically increases performance.
|
|
* Adds `permutationHeap` method for computing all permutations of an array.
|
|
* Adds `combinations` for combinations without replacement
|
|
* Adds `combinationsReplacement` for combinations with replacement
|
|
|
|
## 2.1.0
|
|
|
|
* Adds `bisect` method that implements the [bisection method](https://en.wikipedia.org/wiki/Bisection_method)
|
|
for root-finding. Thanks [Jamie Neubert Pedersen](https://github.com/eikooc)
|
|
for the contribution!
|
|
|
|
## 2.0.0
|
|
|
|
New features:
|
|
|
|
* `product`: returns the product of a series of numbers
|
|
* `medianSorted`: exposes the internal method of `median`
|
|
that only operates on sorted arrays and works in constant time
|
|
* `modeSorted`: exposes the internal method of `mode` and works
|
|
in linear time.
|
|
|
|
Specifications:
|
|
|
|
* Adds [Flow](http://flowtype.org/) annotations to all methods, allowing
|
|
up-front typechecking if you use Flow in your application.
|
|
|
|
Changes:
|
|
|
|
* Invalid input now uniformly produces the value `NaN` instead
|
|
of previously a mix of `null` and `undefined`.
|
|
* The method `sortedUniqueCount` is now called `uniqueCountSorted` to
|
|
match the other sorted methods, `medianSorted` and `modeSorted`
|
|
|
|
Fixes:
|
|
|
|
* `equalIntervalBreaks` was not exported by `index.js`, and now is.
|
|
|
|
## 1.0.1
|
|
|
|
Fixes:
|
|
|
|
* Fixes to ckmeans algorithm (thanks to @llimllib) (#125)
|
|
|
|
Housekeeping:

|
|
* Use bundle-collapser for smaller bundles
|
|
* Indicate numericSort as an internal method.
|
|
|
|
## 1.0.0
|
|
|
|
### Breaking Changes
|
|
|
|
* Removed the .m() and .b() shortcuts from the linear regression
|
|
class. Use `.mb().b` and `.mb().m` instead.
|
|
* linearRegression is now a function, and linearRegressionLine is a separate
|
|
function.
|
|
|
|
**UPGRADING**
|
|
|
|
#### Linear Regression
|
|
|
|
Before:
|
|
|
|
```js
|
|
var l = ss.linear_regression().data([[0, 0], [1, 1]]);
|
|
l.line()(0); // 0
|
|
```
|
|
|
|
After:
|
|
|
|
```js
|
|
var line = ss.linearRegressionLine(ss.linearRegression([[0, 0], [1, 1]]));
|
|
line(0); // 0
|
|
```
|
|
|
|
#### Jenks -> ckmeans
|
|
|
|
The implementation of Jenks natural breaks was removed: an implementation
|
|
of Ckmeans, an improvement on its technique, is added. Ckmeans should
|
|
work better for nearly all Jenks usecases.
|
|
|
|
Before:
|
|
|
|
```js
|
|
ss.jenks([1, 2, 4, 5, 7, 9, 10, 20], 3) //= [1, 7, 20, 20]
|
|
```
|
|
|
|
After:
|
|
|
|
```js
|
|
ss.ckmeans([1, 2, 4, 5, 7, 9, 10, 20], 3))
|
|
|
|
[ [ 1,
|
|
2,
|
|
4,
|
|
5,
|
|
7,
|
|
9 ],
|
|
[ 10 ],
|
|
[ 20 ] ]
|
|
```
|
|
|
|
Instead of class breaks, ckmeans returns clustered data. Class breaks
|
|
can be derived by taking the first value from each cluster:
|
|
|
|
```js
|
|
var breaks = ss.ckmeans([1, 2, 4, 5, 7, 9, 10, 20], 3)).map(function(cluster) {
|
|
return cluster[0];
|
|
});
|
|
```
|
|
|
|
* `BayesModel` is now a class
|
|
* `PerceptronModel` is now a class, and the `weights` and `bias` members
|
|
are accessable as properties rather than methods.
|
|
* All multi-word method names are now camelCase rather than underscore_cased:
|
|
this means that a method like `ss.r_squared` is now accessible as `ss.rSquared`
|
|
|
|
### New Features
|
|
|
|
* Ckmeans replaces Jenks
|
|
* `sortedUniqueCount` provides an extremely fast method for counting
|
|
unique values of sorted arrays.
|
|
* `sumNthPowerDeviations` is now exposed, providing a simple way to calculate
|
|
the fundamental aspect of measures like variance and skewness.
|
|
|
|
### Non-Breaking Changes
|
|
|
|
* JSDoc documentation throughout
|
|
* Each function is now its own file, and simple-statistics
|
|
is assembled with CommonJS-style require() statements. simple-statistics can
|
|
still be used in a browser with browserify.
|
|
* The standard normal table is now calculated using the cumulative distribution
|
|
function, rather than hardcoded.
|
|
|
|
## 0.9.2
|
|
|
|
* Improved test coverage
|
|
* Switched linting from JSHint to [eslint](http://eslint.org/) and fixed
|
|
style issues this uncovered.
|
|
|
|
## 0.9.1
|
|
|
|

|
|
* fixes a bug in `mode` that favored the last new number
|
|
|
|
## 0.8.0
|
|
|
|
* `mixin` can now take an array in order to mixin functions into a single array
|
|
instance rather than the global Array prototype.
|
|
|
|

|
|
|
|
* Adds `simple_statistics.harmonicMean` thanks to [jseppi](https://github.com/jseppi)

|
|
|
|
* Adds `simple_statistics.quantileSorted` thanks to [rluta](http://github.com/rluta)
|
|
* `simple_statistics.quantile` now accepts a sorted list of quantiles as a second argument
