Estimates the arithmetic sample mean and the unbiased population standard deviation from the provided samples as enumerable sequence, in a single pass without memoization.
On a dataset of size N will use an N-1 normalizer (Bessel's correction).
Returns NaN for mean if data is empty or any entry is NaN, and NaN for standard deviation if data has less than two entries or if any entry is NaN.

SyntaxC#
public static (double Mean, double StandardDeviation) MeanStandardDeviation( IEnumerable<float> samples )
Parameters
- samples IEnumerableSingle
- Sample stream, no sorting is assumed.
Return Value
ValueTupleDouble, DoubleA tuple containing the mean and unbiased standard deviation as double. Mean is double.NaN if the stream is empty; standard deviation is double.NaN if there are fewer than two entries or if any entry is NaN.
