On Bessel's correction : unbiased sample variance, the "bariance," and a novel runtime-optimized estimator

Reichel, Felix - 2025

Bessel's correction adjusts the denominator in the sample variance formula from n to n − 1 to produce an unbiased estimator for the population variance. This paper includes rigorous derivations, geometric interpretations, and visualizations. It then introduces the concept of "bariance," an...
