   | Covariance(IEnumerableDouble, IEnumerableDouble) | 
            Estimates the unbiased population covariance from the provided two sample enumerable sequences, in a single pass without memoization.
            On a dataset of size N will use an N-1 normalizer (Bessel's correction).
            Returns NaN if data has less than two entries or if any entry is NaN.
