Statistics operating on an IEnumerable in a single pass, without keeping the full data in memory.
Can be used in a streaming way, e.g. on large datasets not fitting into memory.

The StreamingStatistics type exposes the following members.
Methods| Name | Description | |
|---|---|---|
  | 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. |
| Covariance(IEnumerableSingle, IEnumerableSingle) | 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. |
| Entropy | Calculates the entropy of a stream of double values. Returns NaN if any of the values in the stream are NaN. |
| GeometricMean(IEnumerableDouble) | Evaluates the geometric mean of the enumerable, in a single pass without memoization. Returns NaN if data is empty or any entry is NaN. |
| GeometricMean(IEnumerableSingle) | Evaluates the geometric mean of the enumerable, in a single pass without memoization. Returns NaN if data is empty or any entry is NaN. |
