Description

static KSTest

test(double[] x, double[] y)

The two-sample KS test for the null hypothesis that the data sets are drawn from the same distribution.

static KSTest

test(double[] x, Distribution dist)

The one-sample KS test for the null hypothesis that the data set x is drawn from the given distribution.

Method Details
- test
  
  static KSTest test(double[] x, Distribution dist)
  
  The one-sample KS test for the null hypothesis that the data set x is drawn from the given distribution. Small values of p-value show that the cumulative distribution function of x is significantly different from the given distribution. The array x is modified by being sorted into ascending order.
  
  Parameters:
  
  x - the sample values.
  
  dist - the distribution.
  
  Returns:
  
  the test results.
