KolmogorovSmirnovTest.kolmogorovSmirnovStatistic(RealDistribution distribution,
double[] data)
Computes the one-sample Kolmogorov-Smirnov test statistic, \(D_n=\sup_x |F_n(x)-F(x)|\) where
\(F\) is the distribution (cdf) function associated with
distribution , \(n\) is the
length of data and \(F_n\) is the empirical distribution that puts mass \(1/n\) at
each of the values in data . |
