r2695 r2751 125 125 This estimator fulfills that it is invariant under a rescaling and 126 126 having a weight equal to zero is equivalent to removing the data 127 point. Having all weights equal to unity we get \f$ \sigma=\frac{\sum127 point. Having all weights equal to unity we get \f$ s^2=\frac{\sum 128 128 (x_i-m)^2}{N} \f$, which is the same as returned from Averager. Hence, 129 129 this estimator is slightly biased, but still very efficient.
