+# incrmminmaxabs
+
+> Compute moving minimum and maximum absolute values incrementally.
+
+
+
+## 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() );
+```
