Enclosing class:

KolmogorovDistribution

public static class KolmogorovDistribution.CDF
extends KolmogorovDistribution
implements ClosedFormCumulativeDistributionFunction<java.lang.Double>

Contains the Cumulative Distribution Function description for the "D" statistic used within the Kolmogorov-Smirnov test. This is taken from the probks() method from Numerical Recipes in C, p. 626.

public static double evaluate(double input)

This is the probks() function from Numerical Recipes in C, pp. 626 The NR probks() function actually computes the complement to the CDF, so all the return values in this method will be 1.0-NR, when comparing the code to the NR code.

Parameters:

input - Value at which to evaluate the CDF

Returns:

CDF value at the input

getCDF

public KolmogorovDistribution.CDF getCDF()

Description copied from interface: UnivariateDistribution

Gets the CDF of a scalar distribution.

Specified by:

getCDF in interface ClosedFormUnivariateDistribution<java.lang.Double>

Specified by:

getCDF in interface UnivariateDistribution<java.lang.Double>

Overrides:

getCDF in class KolmogorovDistribution

Returns:

CDF of the scalar distribution.
