Syntax

public MannWhitneyDistribution(
	double[] ranks1,
	double[] ranks2,
	Nullable<bool> exact = null
)

Public Sub New ( 
	ranks1 As Double(),
	ranks2 As Double(),
	Optional exact As Nullable(Of Boolean) = Nothing
)

ranks1: Type: SystemDouble
The global rank statistics for the first sample.
ranks2: Type: SystemDouble
The global rank statistics for the second sample.
exact (Optional): Type: SystemNullableBoolean
True to compute the exact distribution. May require a significant amount of processing power for large samples (n > 30). If left at null, whether to compute the exact or approximate distribution will depend on the number of samples.
