Normal
Normal distribution.
Usage
var normal = require( '@stdlib/stats/base/dists/normal' );
normal
Normal distribution.
var dist = normal;
// returns {...}
The namespace contains the following distribution functions:
cdf( x, mu, sigma ): normal distribution cumulative distribution function.logpdf( x, mu, sigma ): evaluate the natural logarithm of the probability density function (PDF) for a normal distribution.mgf( t, mu, sigma ): normal distribution moment-generating function (MGF).pdf( x, mu, sigma ): normal distribution probability density function (PDF).quantile( p, mu, sigma ): normal distribution quantile function.
The namespace contains the following functions for calculating distribution properties:
entropy( mu, sigma ): normal distribution differential entropy.kurtosis( mu, sigma ): normal distribution excess kurtosis.mean( mu, sigma ): normal distribution expected value.median( mu, sigma ): normal distribution median.mode( mu, sigma ): normal distribution mode.skewness( mu, sigma ): normal distribution skewness.stdev( mu, sigma ): normal distribution standard deviation.variance( mu, sigma ): normal distribution variance.
The namespace contains a constructor function for creating a normal distribution object.
Normal( [mu, sigma] ): normal distribution constructor.
var Normal = require( '@stdlib/stats/base/dists/normal' ).Normal;
var dist = new Normal( 2.0, 4.0 );
var y = dist.pdf( 2.0 );
// returns ~0.1
Examples
var objectKeys = require( '@stdlib/utils/keys' );
var normal = require( '@stdlib/stats/base/dists/normal' );
console.log( objectKeys( normal ) );
