Hi,
i need to calculate the p-value given the kolmogorv smirnov test statistic (two
sided). When I look at the function ks.test I found the following function
which calls C code:
pkstwo <- function(x, tol = 1e-06) {
if (is.numeric(x))
x <- as.vector(x)
else stop("Argument x must be numeric")
p <- rep(0, length(x))
p[is.na(x)] <- NA
IND <- which(!is.na(x) & (x > 0))
if (length(IND) > 0) {
p[IND] <- .C("pkstwo", as.integer(length(x)), p = as.double(x[IND]),
as.double(tol), PACKAGE = "ctest")$p
}
return(p)
}
Extracting and using this function, I get the following error message:
Error in .C("pkstwo", as.integer(length(x)), p = as.double(x[IND]),
as.double(tol), :
C entry point "pkstwo" not in DLL for package "ctest"
Any suggestions (perhaps a small example) how to calculate the p-value for the
KS-statistic (without using ks.test()!!!). Help is welcome.
Regards
Jaci
