About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
Uniform distribution constructor.
import Uniform from 'https://cdn.jsdelivr.net/gh/stdlib-js/stats-base-dists-uniform-ctor@esm/index.mjs';
Returns an uniform distribution object.
var uniform = new Uniform();
var mu = uniform.mean;
// returns 0.5
By default, a = 0.0
and b = 1.0
. To create a distribution having a different a
(minimum support) and b
(maximum support), provide the corresponding arguments.
var uniform = new Uniform( 2.0, 4.0 );
var mu = uniform.mean;
// returns 3.0
An uniform distribution object has the following properties and methods...
Minimum support of the distribution. a
must be a number smaller than b
.
var uniform = new Uniform();
var a = uniform.a;
// returns 0.0
uniform.a = 0.5;
a = uniform.a;
// returns 0.5
Maximum support of the distribution. b
must be a number larger than a
.
var uniform = new Uniform( 2.0, 4.0 );
var b = uniform.b;
// returns 4.0
uniform.b = 3.0;
b = uniform.b;
// returns 3.0
Returns the differential entropy.
var uniform = new Uniform( 4.0, 12.0 );
var entropy = uniform.entropy;
// returns ~2.079
Returns the excess kurtosis.
var uniform = new Uniform( 4.0, 12.0 );
var kurtosis = uniform.kurtosis;
// returns -1.2
Returns the expected value.
var uniform = new Uniform( 4.0, 12.0 );
var mu = uniform.mean;
// returns 8.0
Returns the median.
var uniform = new Uniform( 4.0, 12.0 );
var median = uniform.median;
// returns 8.0
Returns the skewness.
var uniform = new Uniform( 4.0, 12.0 );
var skewness = uniform.skewness;
// returns 0.0
Returns the standard deviation.
var uniform = new Uniform( 4.0, 12.0 );
var s = uniform.stdev;
// returns ~2.309
Returns the variance.
var uniform = new Uniform( 4.0, 12.0 );
var s2 = uniform.variance;
// returns ~5.333
Evaluates the cumulative distribution function (CDF).
var uniform = new Uniform( 2.0, 4.0 );
var y = uniform.cdf( 2.5 );
// returns 0.25
Evaluates the natural logarithm of the cumulative distribution function (CDF).
var uniform = new Uniform( 2.0, 4.0 );
var y = uniform.logcdf( 2.5 );
// returns ~-1.386
Evaluates the natural logarithm of the probability density function (PDF).
var uniform = new Uniform( 2.0, 4.0 );
var y = uniform.logpdf( 2.5 );
// returns ~-0.693
Evaluates the probability density function (PDF).
var uniform = new Uniform( 2.0, 4.0 );
var y = uniform.pdf( 2.5 );
// returns 0.5
Evaluates the quantile function at probability p
.
var uniform = new Uniform( 2.0, 4.0 );
var y = uniform.quantile( 0.5 );
// returns 3.0
y = uniform.quantile( 1.9 );
// returns NaN
