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