## Usage
```javascript
var cosine = require( '@stdlib/stats/base/dists/cosine' );
```
#### cosine
Raised cosine distribution.
```javascript
var dist = cosine;
// returns {...}
```
The namespace contains the following distribution functions:
- [`cdf( x, mu, s )`][@stdlib/stats/base/dists/cosine/cdf]: raised cosine distribution cumulative distribution function.
- [`logcdf( x, mu, s )`][@stdlib/stats/base/dists/cosine/logcdf]: evaluate the natural logarithm of the cumulative distribution function (CDF) for a raised cosine distribution.
- [`logpdf( x, mu, s )`][@stdlib/stats/base/dists/cosine/logpdf]: raised cosine distribution logarithm of probability density function (PDF).
- [`mgf( t, mu, s )`][@stdlib/stats/base/dists/cosine/mgf]: raised cosine distribution moment-generating function.
- [`pdf( x, mu, s )`][@stdlib/stats/base/dists/cosine/pdf]: raised cosine distribution probability density function (PDF).
- [`quantile( p, mu, s )`][@stdlib/stats/base/dists/cosine/quantile]: raised cosine distribution quantile function.
The namespace contains the following functions for calculating distribution properties:
- [`kurtosis( mu, s )`][@stdlib/stats/base/dists/cosine/kurtosis]: raised cosine distribution excess kurtosis.
- [`mean( mu, s )`][@stdlib/stats/base/dists/cosine/mean]: raised cosine distribution expected value.
- [`median( mu, s )`][@stdlib/stats/base/dists/cosine/median]: raised cosine distribution median.
- [`mode( mu, s )`][@stdlib/stats/base/dists/cosine/mode]: raised cosine distribution mode.
- [`skewness( mu, s )`][@stdlib/stats/base/dists/cosine/skewness]: raised cosine distribution skewness.
- [`stdev( mu, s )`][@stdlib/stats/base/dists/cosine/stdev]: raised cosine distribution standard deviation.
- [`variance( mu, s )`][@stdlib/stats/base/dists/cosine/variance]: raised cosine distribution variance.
The namespace contains a constructor function for creating a [raised cosine][cosine-distribution] distribution object.
- [`Cosine( [mu, s] )`][@stdlib/stats/base/dists/cosine/ctor]: raised cosine distribution constructor.
```javascript
var Cosine = require( '@stdlib/stats/base/dists/cosine' ).Cosine;
var dist = new Cosine( 2.0, 4.0 );
var y = dist.cdf( 0.5 );
// returns ~0.165
