+ +## Usage + +```javascript +var incrnanmminmaxabs = require( '@stdlib/stats/incr/mminmaxabs' ); +``` + +#### incrnanmminmaxabs( \[out,] window ) + +Returns an accumulator `function` which incrementally computes moving minimum and maximum absolute values, ignoring `NaN` values. The `window` parameter defines the number of values over which to compute moving minimum and maximum absolute values. + +```javascript +var accumulator = incrnanmminmaxabs( 3 ); +``` + +By default, the returned accumulator `function` returns the minimum and maximum as a two-element `array`. To avoid unnecessary memory allocation, the function supports providing an output (destination) object. + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +var accumulator = incrnanmminmaxabs( new Float64Array( 2 ), 3 ); +``` + +#### accumulator( \[x] ) + +If provided an input value `x`, the accumulator function returns updated minimum and maximum absolute values. If not provided an input value `x`, the accumulator function returns the current minimum and maximum absolute values. + +```javascript +var accumulator = incrnanmminmaxabs( 3 ); + +var mm = accumulator(); +// returns null + +// Fill the window... +mm = accumulator( 2.0 ); // [2.0] +// returns [ 2.0, 2.0 ] + +mm = accumulator( 1.0 ); // [2.0, 1.0] +// returns [ 1.0, 2.0 ] + +mm = accumulator( 3.0 ); // [2.0, 1.0, 3.0] +// returns [ 1.0, 3.0 ] + +// Window begins sliding... +mm = accumulator( -7.0 ); // [1.0, 3.0, -7.0] +// returns [ 1.0, 7.0 ] + +mm = accumulator( -5.0 ); // [3.0, -7.0, -5.0] +// returns [ 3.0, 7.0 ] + +mm = accumulator(); +// returns [ 3.0, 7.0 ] +``` + +
+ + + +
+ +## Notes + +- Input values are **not** type checked. 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 minimum and maximum values are calculated from smaller sample sizes. Until the window is full, each returned minimum and maximum is calculated from all provided values. + +
+ + + +
+ +## Examples + + + +```javascript +var randu = require( '@stdlib/random/base/randu' ); +var incrnanmminmaxabs = require( '@stdlib/stats/incr/mminmaxabs' ); + +var accumulator; +var v; +var i; + +// Initialize an accumulator: +accumulator = incrnanmminmaxabs( 5 ); + +// For each simulated datum, update the moving minimum and maximum absolute values... +for ( i = 0; i < 100; i++ ) { + v = ( randu()*100.0 ) - 50.0; + accumulator( v ); +} +console.log( accumulator() ); +``` + +
