Planck

Planck distribution.

Installation

npm install @stdlib/stats-base-dists-planck

Usage

var planck = require( '@stdlib/stats-base-dists-planck' );

planck

Planck distribution.

var dist = planck;
// returns {...}

The namespace contains the following distribution functions:

• cdf( x, lambda ): planck (discrete exponential) distribution cumulative distribution function.
• logcdf( x, lambda ): evaluate the logarithm of the cumulative distribution function for a Planck (discrete exponential) distribution.
• logpmf( x, lambda ): evaluate the logarithm of the probability mass function (PMF) for a Planck (discrete exponential) distribution.
• mgf( t, lambda ): planck (discrete exponential) distribution moment-generating function (MGF).
• pmf( x, lambda ): planck (discrete exponential) distribution probability mass function (PMF).
• quantile( p, lambda ): planck (discrete exponential) distribution quantile function.

The namespace contains the following functions for calculating distribution properties:

• entropy( lambda ): planck (discrete exponential) distribution differential entropy.
• kurtosis( lambda ): planck (discrete exponential) distribution excess kurtosis.
• mean( lambda ): planck distribution expected value.
• median( lambda ): planck (discrete exponential) distribution median.
• mode( lambda ): planck (discrete exponential) distribution mode.
• skewness( lambda ): planck (discrete exponential) distribution skewness.
• stdev( lambda ): planck distribution standard deviation.
• variance( lambda ): planck distribution variance.

Examples

var objectKeys = require( '@stdlib/utils-keys' );
var planck = require( '@stdlib/stats-base-dists-planck' );

console.log( objectKeys( planck ) );
