Detailed Description

template<typename Sum = ntg::float_s, typename Var = ntg::float_s>
class oln::utils::se_stat< Sum, Var >

Compute the variance and the mean within a window.

Parameters:

Sum	type used to compute the sum and the average.
Var	type used to compute the variance.

Note:

There are two parameters because for vectorial types the sum is usually a vector, and the variance a non vectorial type.
