## Class KolmogorovSmirnovDist

• java.lang.Object
• jhplot.math.KolmogorovSmirnovDist

• `public class KolmogorovSmirnovDistextends java.lang.Object`

This class computes both the cumulative probability P[D_n <= x] and the complementary cumulative probability P[D_n >= x] of the 2-sided 1-sample Kolmogorov-Smirnov distribution.

The Kolmogorov-Smirnov test statistic D_n is defined by

D_n = sup_x |F(x) - S_n(x)|

where n is the sample size, S_n(x) is an empirical distribution function, and F(x) is a completely specified theoretical distribution.

• #### cdf

`public static double cdf(int n,                         double x)`
Computes the cumulative probability P[D_n <= x] of the Kolmogorov-Smirnov distribution with sample size n at x. It returns at least 13 decimal digits of precision for n <= 140, at least 5 decimal digits of precision for 140 < n <= 100000, and a few correct decimal digits for n > 100000.
Parameters:
`n` - sample size
`x` - value of Kolmogorov-Smirnov statistic
Returns:
cumulative probability
• #### fbar

`public static double fbar(int n,                          double x)`
Computes the complementary cumulative probability P[D_n >= x] of the Kolmogorov-Smirnov distribution with sample size n at x. It returns at least 10 decimal digits of precision for n <= 140, at least 5 decimal digits of precision for 140 < n <= 200000, and a few correct decimal digits for n > 200000.
Parameters:
`n` - sample size
`x` - value of Kolmogorov-Smirnov statistic
Returns:
complementary cumulative probability
• #### main

`public static void main(java.lang.String[] args)`
