function dvarmpn( N, mean, correction, x, strideX, offsetX ) {
	return addon.ndarray( N, mean, correction, x, strideX, offsetX );
}
Computes the variance of a double-precision floating-point strided array provided a known mean and using Neely's correction algorithm.

@param {PositiveInteger} N - number of indexed elements
@param {number} mean - mean
@param {number} correction - degrees of freedom adjustment
@param {Float64Array} x - input array
@param {integer} strideX - stride length
@param {NonNegativeInteger} offsetX - starting index
@returns {number} variance

@example
var Float64Array = require( '@stdlib/array/float64' );

var x = new Float64Array( [ 2.0, 1.0, 2.0, -2.0, -2.0, 2.0, 3.0, 4.0 ] );

var v = dvarmpn( 4, 1.25, 1, x, 2, 1 );
// returns 6.25
