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!

incrmrange

> Compute a moving range incrementally.

The range is defined as the difference between the maximum and minimum values.

Installation

npm install @stdlib/stats-incr-mrange

Usage

var incrmrange = require( '@stdlib/stats-incr-mrange' );

incrmrange( window )

Returns an accumulator function which incrementally computes a moving range. The window parameter defines the number of values over which to compute the moving range.

var accumulator = incrmrange( 3 );

accumulator( [x] )

If provided an input value x, the accumulator function returns an updated range. If not provided an input value x, the accumulator function returns the current range.

var accumulator = incrmrange( 3 );

var r = accumulator();
// returns null

// Fill the window...
r = accumulator( 2.0 ); // [2.0]
// returns 0.0

r = accumulator( 1.0 ); // [2.0, 1.0]
// returns 1.0

r = accumulator( 3.0 ); // [2.0, 1.0, 3.0]
// returns 2.0

// Window begins sliding...
r = accumulator( -7.0 ); // [1.0, 3.0, -7.0]
// returns 10.0

r = accumulator( -5.0 ); // [3.0, -7.0, -5.0]
// returns 10.0

r = accumulator();
// returns 10.0

Notes

Input values are not type checked. If provided NaN, the accumulated value is NaN for at least W-1 future invocations. If non-numeric inputs are possible, you are advised to type check and handle accordingly before passing the value to the accumulator function.
As W values are needed to fill the window buffer, the first W-1 returned values are calculated from smaller sample sizes. Until the window is full, each returned value is calculated from all provided values.

Examples

var randu = require( '@stdlib/random-base-randu' );
var incrmrange = require( '@stdlib/stats-incr-mrange' );

var accumulator;
var v;
var i;

// Initialize an accumulator:
accumulator = incrmrange( 5 );

// For each simulated datum, update the moving range...
for ( i = 0; i &lt; 100; i++ ) {
    v = randu() * 100.0;
    accumulator( v );
}
console.log( accumulator() );

Notice

This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
