	variances As Double(),
	Optional unbiased As Boolean = true
) As Double

sizes: Type: SystemInt32
The number of samples used to compute the variances.
variances: Type: SystemDouble
The unbiased variances for the samples.
unbiased (Optional): Type: SystemBoolean
True to compute a pooled standard deviation using unbiased estimates of the population variance; false otherwise. Default is true.
