    125125This estimator fulfills that it is invariant under a rescaling and
    126126having a weight equal to zero is equivalent to removing the data
    127 point. Having all weights equal to unity we get \f$ \sigma=\frac{\sum
     127point. Having all weights equal to unity we get \f$ s^2=\frac{\sum
    128128(x_i-m)^2}{N} \f$, which is the same as returned from Averager. Hence,
    129129this estimator is slightly biased, but still very efficient.
