ks.test does not produce the correct output.
If given the script:
d1 <-
c(53.63984674,0.383141762,1.915708812,0.383141762,10.72796935,6.896551724,20.30651341,5.747126437,0)
d1
d2 <-
c(76.43312102,15.2866242,3.821656051,1.27388535,0,0.636942675,1.27388535,0.636942675,0.636942675)
d2
ks.test(d1,d2,alternative="two.sided",exact)
The output generates:
Two-sample Kolmogorov-Smirnov test
data: dd and ddd
D = 0.3333, p-value = 0.6994
alternative hypothesis: two.sided
Warning message:
cannot compute correct p-values with ties in: ks.test(dd, ddd, alternative =
"two.sided", exact)
Which is far from the correct D value of:
D = 0.404934475 with a p-value < 0.01
I recommend that noone use this test. I have tested it with various datasets
from publications and texts using by-hand calculations.
