Student's T

Student's t distribution.

Usage

var t = require( '@stdlib/stats/base/dists/t' );

t

Student's t distribution.

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

The namespace contains the following distribution functions:

• cdf( x, v ): Student's t distribution cumulative distribution function (CDF).
• logcdf( x, v ): evaluate the natural logarithm of the cumulative distribution function (CDF) for a Student's t distribution.
• logpdf( x, v ): evaluate the natural logarithm of the probability density function (PDF) for a Student's t distribution.
• pdf( x, v ): Student's t distribution probability density function (PDF).
• quantile( p, v ): Student's t distribution quantile function.

The namespace contains the following functions for calculating distribution properties:

• entropy( v ): Student's t distribution differential entropy.
• kurtosis( v ): Student's t distribution excess kurtosis.
• mean( v ): Student's t distribution expected value.
• median( v ): Student's t distribution median.
• mode( v ): Student's t distribution mode.
• skewness( v ): Student's t distribution skewness.
• stdev( v ): Student's t distribution variance.
• variance( v ): Student's t distribution variance.

The namespace contains a constructor function for creating a Student's t distribution object.

• T( [v] ): Student's t distribution constructor.

var T = require( '@stdlib/stats/base/dists/t' ).T;

var dist = new T( 2.0 );

var y = dist.cdf( 0.5 );
// returns ~0.667

Examples

var objectKeys = require( '@stdlib/utils/keys' );
var t = require( '@stdlib/stats/base/dists/t' );

console.log( objectKeys( t ) );
