Truncated Normal

Truncated normal distribution.

Usage

var truncatedNormal = require( '@stdlib/stats/base/dists/truncated-normal' );

truncatedNormal

Truncated normal distribution.

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

The namespace contains the following distribution functions:

pdf( x, a, b, mu, sigma ): truncated normal distribution probability density function (PDF).

The namespace contains the following functions for calculating distribution properties:

The namespace contains a constructor function for creating a truncated normal distribution object.

Examples

var truncatedNormal = require( '@stdlib/stats/base/dists/truncated-normal' );

/*
* Let's consider an example where we're modeling the heights of astronauts.
* We'll use the truncated normal distribution to model this scenario, considering constraints on their minimum and maximum heights.
* The distribution has parameters: a (minimum height), b (maximum height), mu (location parameter), and sigma (scale parameter).
* In this example, we'll assume a = 150 (minimum height), b = 200 (maximum height), mu = 175 (location parameter), and sigma = 10 (scale parameter).
*/

var a = 150.0;
var b = 200.0;
var mu = 175.0;
var sigma = 10.0;

// Calculate the probability density function (PDF) for a height of 180 cm:
console.log( truncatedNormal.pdf( 180, a, b, mu, sigma ) );
// => ~0.036
