Population variance should be available as enumerable extension

Reported by: mkommend Owned by: mkommend
Priority: medium Milestone: HeuristicLab 3.3.14
Component: Common Version: 3.3.13
Keywords: Cc:


Currently only the sample standard deviation and variance can be calculated with the enumerable extensions. The difference between those is the divisor n vs (n-1).

r14011 slightly changes the existing behavior of the sample stddev and variance.

previously: variance(Enumerable<double>.Empty) == 0.0 now: variance(Enumerable<double>.Empty == double.NaN
