In sfsmisc: Utilities from 'Seminar fuer Statistik' ETH Zurich

Approximate Critical Values for Kolmogorov-Smirnov's D

Description

Computes the critical value for Kolmogorov-Smirnov's D_n, for sample sizes n \ge 10 and confidence level 95%.

Usage

KSd(n)

Arguments

n	the sample size, n >= 10.

Details

Based on tables values given in the reference below. For n\le 80 uses interpolations from exact values, elsewhere uses asymptotic approximation.

Value

The critical value for D (two-sided) for significance level 0.05 (or confidence level 95%).

Examples

KSd(90)
KSd(1:9)# now works

op <- par(mfrow=c(2,1))
  plot(KSd, 10, 150)# nice
  abline(v = c(75,85), col = "gray")
  plot(KSd, 79, 81, n = 1001)# *very* tiny discontinuity at 80
par(op)
