## Usage
```javascript
var gamma = require( '@stdlib/stats/base/dists/gamma' );
```
#### gamma
Gamma distribution.
```javascript
var dist = gamma;
// returns {...}
```
The namespace contains the following distribution functions:
- [`cdf( x, alpha, beta )`][@stdlib/stats/base/dists/gamma/cdf]: gamma distribution cumulative distribution function.
- [`logcdf( x, alpha, beta )`][@stdlib/stats/base/dists/gamma/logcdf]: gamma distribution logarithm of cumulative distribution function (CDF).
- [`logpdf( x, alpha, beta )`][@stdlib/stats/base/dists/gamma/logpdf]: gamma distribution logarithm of probability density function (PDF).
- [`mgf( t, alpha, beta )`][@stdlib/stats/base/dists/gamma/mgf]: gamma distribution moment-generating function (MGF).
- [`pdf( x, alpha, beta )`][@stdlib/stats/base/dists/gamma/pdf]: gamma distribution probability density function (PDF).
- [`quantile( p, alpha, beta )`][@stdlib/stats/base/dists/gamma/quantile]: gamma distribution quantile function.
The namespace contains the following functions for calculating distribution properties:
- [`entropy( alpha, beta )`][@stdlib/stats/base/dists/gamma/entropy]: gamma distribution differential entropy.
- [`kurtosis( alpha, beta )`][@stdlib/stats/base/dists/gamma/kurtosis]: gamma distribution excess kurtosis.
- [`mean( alpha, beta )`][@stdlib/stats/base/dists/gamma/mean]: gamma distribution expected value.
- [`mode( alpha, beta )`][@stdlib/stats/base/dists/gamma/mode]: gamma distribution mode.
- [`skewness( alpha, beta )`][@stdlib/stats/base/dists/gamma/skewness]: gamma distribution skewness.
- [`stdev( alpha, beta )`][@stdlib/stats/base/dists/gamma/stdev]: gamma distribution standard deviation.
- [`variance( alpha, beta )`][@stdlib/stats/base/dists/gamma/variance]: gamma distribution variance.
The namespace contains a constructor function for creating a [gamma][gamma-distribution] distribution object.
- [`Gamma( [alpha, beta] )`][@stdlib/stats/base/dists/gamma/ctor]: gamma distribution constructor.
```javascript
var Gamma = require( '@stdlib/stats/base/dists/gamma' ).Gamma;
var dist = new Gamma( 2.0, 4.0 );
var y = dist.cdf( 0.5 );
// returns ~0.594
