* Computes the standard deviation of a strided array ignoring `NaN` values and using a one-pass algorithm proposed by Youngs and Cramer.

* @param {number} correction - degrees of freedom adjustment
* @param {NumericArray} x - input array
* @param {integer} strideX - stride length

* @example

*
* var v = nanstdevyc( 4, 1, x, 1 );
* // returns ~2.0817
