nanmax

Calculate the maximum value of an array, ignoring NaN values.

Usage

var nanmax = require( '@stdlib/stats/array/nanmax' );

nanmax( x )

Computes the maximum value of an array, ignoring NaN values.

var x = [ 1.0, -2.0, NaN, 2.0 ];

var v = nanmax( x );
// returns 2.0

The function has the following parameters:

• x: input array.

Notes

• If provided an empty array, the function returns NaN.
• The function supports array-like objects having getter and setter accessors for array element access (e.g., @stdlib/array/base/accessor).

Examples

var uniform = require( '@stdlib/random/base/uniform' );
var bernoulli = require( '@stdlib/random/base/bernoulli' );
var filledarrayBy = require( '@stdlib/array/filled-by' );
var nanmax = require( '@stdlib/stats/array/nanmax' );

function rand() {
    if ( bernoulli( 0.8 ) < 1 ) {
        return NaN;
    }
    return uniform( -50.0, 50.0 );
}

var x = filledarrayBy( 10, 'float64', rand );
console.log( x );

var v = nanmax( x );
console.log( v );
