# incrminabs
> Compute a minimum absolute value incrementally.
## Usage
```javascript
var incrminabs = require( '@stdlib/stats/incr/minabs' );
```
#### incrminabs()
Returns an accumulator `function` which incrementally computes a minimum absolute value.
```javascript
var accumulator = incrminabs();
```
#### accumulator( \[x] )
If provided an input value `x`, the accumulator function returns an updated minimum absolute value. If not provided an input value `x`, the accumulator function returns the current minimum absolute value.
```javascript
var accumulator = incrminabs();
var min = accumulator( 2.0 );
// returns 2.0
min = accumulator( 1.0 );
// returns 1.0
min = accumulator( -3.0 );
// returns 1.0
min = accumulator();
// returns 1.0
```
## Notes
- Input values are **not** type checked. If provided `NaN`, the accumulated value is `NaN` for **all** 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.
## Examples
```javascript
var randu = require( '@stdlib/random/base/randu' );
var incrminabs = require( '@stdlib/stats/incr/minabs' );
var accumulator;
var v;
var i;
// Initialize an accumulator:
accumulator = incrminabs();
// For each simulated datum, update the minimum absolute value...
for ( i = 0; i < 100; i++ ) {
v = ( randu()*100.0 ) - 50.0;
accumulator( v );
}
console.log( accumulator() );
```
