+ +The [**mid-range**][mid-range], or **mid-extreme**, is the arithmetic mean of the maximum and minimum values in a data set. The measure is the midpoint of the range and a measure of central tendency. + +
+ + + +
+ +## Usage + +```javascript +var midrangeBy = require( '@stdlib/stats/strided/midrange-by' ); +``` + +#### midrangeBy( N, x, strideX, clbk\[, thisArg] ) + +Computes the [mid-range][mid-range] of a strided array via a callback function. + +```javascript +function accessor( v ) { + return v * 2.0; +} + +var x = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ]; + +var v = midrangeBy( x.length, x, 1, accessor ); +// returns -1.0 +``` + +The function has the following parameters: + +- **N**: number of indexed elements. +- **x**: input [`Array`][mdn-array], [`typed array`][mdn-typed-array], or an array-like object (excluding strings and functions). +- **strideX**: stride length. +- **clbk**: callback function. +- **thisArg**: execution context (_optional_). + +The invoked callback is provided four arguments: + +- **value**: array element. +- **aidx**: array index. +- **sidx**: strided index (`offset + aidx*stride`). +- **array**: input array/collection. + +To set the callback execution context, provide a `thisArg`. + +```javascript +function accessor( v ) { + this.count += 1; + return v * 2.0; +} + +var x = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ]; + +var context = { + 'count': 0 +}; + +var v = midrangeBy( x.length, x, 1, accessor, context ); +// returns -1.0 + +var cnt = context.count; +// returns 8 +``` + +The `N` and stride parameters determine which elements in the strided array are accessed at runtime. For example, to access every other element + +```javascript +function accessor( v ) { + return v * 2.0; +} + +var x = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ]; + +var v = midrangeBy( 4, x, 2, accessor ); +// returns 2.0 +``` + +Note that indexing is relative to the first index. To introduce an offset, use [`typed array`][mdn-typed-array] views. + +```javascript +var Float64Array = require( '@stdlib/array/float64' ); + +function accessor( v ) { + return v * 2.0; +} + +// Initial array... +var x0 = new Float64Array( [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ] ); + +// Create an offset view... +var x1 = new Float64Array( x0.buffer, x0.BYTES_PER_ELEMENT*1 ); // start at 2nd element + +// Access every other element... +var v = midrangeBy( 3, x1, 2, accessor ); +// returns -8.0 +``` + +#### midrangeBy.ndarray( N, x, strideX, offsetX, clbk\[, thisArg] ) + +Computes the [mid-range][mid-range] of a strided array via a callback function and using alternative indexing semantics. + +```javascript +function accessor( v ) { + return v * 2.0; +} + +var x = [ -2.0, 1.0, 3.0, -5.0, 4.0, 0.0, -1.0, -3.0 ]; + +var v = midrangeBy.ndarray( x.length, x, 1, 0, accessor ); +// returns -1.0 +``` + +The function has the following additional parameters: + +- **offsetX**: starting index. + +While [`typed array`][mdn-typed-array] views mandate a view offset based on the underlying buffer, the offset parameter supports indexing semantics based on a starting index. For example, to access only the last three elements of `x` + +```javascript +function accessor( v ) { + return v * 2.0; +} + +var x = [ 1.0, -2.0, 3.0, -4.0, 5.0, -6.0 ]; + +var v = midrangeBy.ndarray( 3, x, 1, x.length-3, accessor ); +// returns -1.0 +``` + +
+ + + +
+ +## Notes + +- If `N <= 0`, both functions return `NaN`. +- A provided callback function should return a numeric value. +- If a provided callback function does not return any value (or equivalently, explicitly returns `undefined`), the value is **ignored**. +- Both functions support array-like objects having getter and setter accessors for array element access (e.g., [`@stdlib/array/base/accessor`][@stdlib/array/base/accessor]). +- When possible, prefer using [`midrange`][@stdlib/stats/strided/midrange], as, depending on the environment, it is likely to be significantly more performant. + +
+ + + +
+ +## Examples + + + +```javascript +var discreteUniform = require( '@stdlib/random/array/discrete-uniform' ); +var midrangeBy = require( '@stdlib/stats/strided/midrange-by' ); + +function accessor( v ) { + return v * 2.0; +} + +var x = discreteUniform( 10, -50, 50, { + 'dtype': 'float64' +}); +console.log( x ); + +var v = midrangeBy( x.length, x, 1, accessor ); +console.log( v ); +``` + +
