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