Detailed Description

Find the variance of a filtered vector.

Note

D - any protection domain

Supported types - int32 / int64 / float32 / float64

Parameters

data	- input vector (the function may overflow if the input is too big)
mask	- mask indicating which elements of the input vector to include when computing the variance

Returns

returns the variance of the input vector

Leakage

None
