Public Methods

Method Description
Clone ( ) : object

Creates a new object that is a copy of the current instance.

DistributionFunction ( double w ) : double

Gets the cumulative distribution function (cdf) for this distribution evaluated at point k.

The Cumulative Distribution Function (CDF) describes the cumulative probability that a given value or any value smaller than it will occur.

InverseDistributionFunction ( double p ) : double

Gets the inverse of the cumulative distribution function (icdf) for this distribution evaluated at probability p. This function is also known as the Quantile function.

LogProbabilityDensityFunction ( double w ) : double

Gets the log-probability density function (pdf) for this distribution evaluated at point w.

The Probability Density Function (PDF) describes the probability that a given value x will occur.

ProbabilityDensityFunction ( double w ) : double

Gets the probability density function (pdf) for this distribution evaluated at point w.

The Probability Density Function (PDF) describes the probability that a given value x will occur.

ToString ( string format, IFormatProvider formatProvider ) : string

Returns a System.String that represents this instance.

WMinimum ( int signs, double ranks ) : double

Computes the Wilcoxon's W statistic.

The W statistic is computed as the minimum of the W+ and W- statistics.

WNegative ( int signs, double ranks ) : double

Computes the Wilcoxon's W- statistic.

The W- statistic is computed as the sum of all negative signed ranks.

WPositive ( int signs, double ranks ) : double

Computes the Wilcoxon's W+ statistic.

The W+ statistic is computed as the sum of all positive signed ranks.

WilcoxonDistribution ( double ranks ) : System

Creates a new Wilcoxon's W+ distribution.

WilcoxonDistribution ( double ranks, bool forceExact ) : System

Creates a new Wilcoxon's W+ distribution.
