Struct template lazy_weighted_variance_impl
boost::accumulators::impl::lazy_weighted_variance_impl — Lazy calculation of variance of weighted samples.
Synopsis
Description
The default implementation of the variance of weighted samples is based on the second moment
(weighted_moment<2>) and the mean
(weighted_mean):
where
is the number of samples.
