WeightedDescriptiveStatistics Class

Computes the basic statistics of data set. The class meets the NIST standard of accuracy for mean, variance, and standard deviation (the only statistics they provide exact values for) and exceeds them in increased accuracy mode. Recommendation: consider to use RunningWeightedStatistics instead.

Properties

	Name	Description
	Count	Gets the size of the sample.
	EffectiveSampleSize	The Kish's effective sample size https://en.wikipedia.org/wiki/Effective_sample_size
	Kurtosis	Gets the unbiased estimator of the population excess kurtosis using the G_2 estimator.
	Maximum	Gets the maximum sample value.
	Mean	Gets the sample mean.
	Minimum	Gets the minimum sample value.
	Skewness	Gets the unbiased estimator of the population skewness.
	StandardDeviation	Gets the unbiased population standard deviation (on a dataset of size N will use an N-1 normalizer).
	TotalWeight	Gets the total weight. When used with unweighted data, returns the number of samples.
	Variance	Gets the unbiased population variance estimator (on a dataset of size N will use an N-1 normalizer).

Methods

	Name	Description
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
	ToString	Returns a string that represents the current object. (Inherited from Object)

Remarks

This type declares a DataContract for out of the box ephemeral serialization with engines like DataContractSerializer, Protocol Buffers and FsPickler, but does not guarantee any compatibility between versions. It is not recommended to rely on this mechanism for durable persistence.
