static float Variance(
	FloatVector^ v
)

static member Variance : 
        v : FloatVector -> float32

Single
The biased variance of the elements in v.

Exceptions

Exception	Condition
InvalidArgumentException	Thrown if v has zero length.

Remarks

variance = (System.Math.pow(v[0] - mean, 2) + System.Math.pow(v[1] - mean, 2)) / n
