## Usage
```javascript
var chi = require( '@stdlib/stats/base/dists/chi' );
```
#### chi
Chi distribution.
```javascript
var dist = chi;
// returns {...}
```
The namespace contains the following distribution functions:
- [`cdf( x, k )`][@stdlib/stats/base/dists/chi/cdf]: Chi distribution cumulative distribution function.
- [`logpdf( x, k )`][@stdlib/stats/base/dists/chi/logpdf]: evaluate the natural logarithm of the probability density function (PDF) for a chi distribution .
- [`pdf( x, k )`][@stdlib/stats/base/dists/chi/pdf]: Chi distribution probability density function (PDF).
- [`quantile( p, k )`][@stdlib/stats/base/dists/chi/quantile]: Chi distribution quantile function.
The namespace contains the following functions for calculating distribution properties:
- [`entropy( k )`][@stdlib/stats/base/dists/chi/entropy]: Chi distribution differential entropy.
- [`kurtosis( k )`][@stdlib/stats/base/dists/chi/kurtosis]: Chi distribution excess kurtosis.
- [`mean( k )`][@stdlib/stats/base/dists/chi/mean]: Chi distribution expected value.
- [`mode( k )`][@stdlib/stats/base/dists/chi/mode]: Chi distribution mode.
- [`skewness( k )`][@stdlib/stats/base/dists/chi/skewness]: Chi distribution skewness.
- [`stdev( k )`][@stdlib/stats/base/dists/chi/stdev]: Chi distribution standard deviation.
- [`variance( k )`][@stdlib/stats/base/dists/chi/variance]: Chi distribution variance.
The namespace contains a constructor function for creating a [Chi][chi-distribution] distribution object.
- [`Chi( [k] )`][@stdlib/stats/base/dists/chi/ctor]: Chi distribution constructor.
```javascript
var Chi = require( '@stdlib/stats/base/dists/chi' ).Chi;
var dist = new Chi( 4.0 );
var mu = dist.mean;
// returns ~1.88
