Flow count variance

We can also compute the variance of the estimates for the number of active flows. We cannot compare against packet sampling because there are no unbiased estimates for the number of active flows based on packet sampled data.

$\displaystyle VAR[\widehat{f}]=(1-p)^{s-1}(1/p-1)$ (9)
