I have been simulating daily in-stream bacteria concentrations using a variety
of scenarios. I am using the ks.test (two sample,two-sided) for analysis. My
data sets are both of equal size (n=64).
My question is this: For the two sample, two sided ks.test, how is the exact
I have not been able to find an explicit citation of how the P-value is
calculated. I have read the help file which cites three publications and
assigns those pubs to one version or another of the ks.test (eg. one sample,
one-sided, etc.). I have also read to the Conover book (referenced but not
cited). Conover tables are adapted from a Birnbaum and Hall (1960) paper, and
then I have also found tables by Kim and Jennrich, but I feel I have found
some disagreement between these sources (with regards to critical D values and
p-values). I would like to compare the methods utilized by R version 2.3.0 on
Can anybody tell me the exact method for calculating the p-value for a
two-sample, two sided ks.test?
Any help would greatly appreciated!
