cUmbrPK: Computes a critical value for the Mack-Wolfe Peak Known A_p distribution.
Description
This function computes the critical value for the Mack-Wolfe Peak Known A_p distribution at (or typically in the "Exact" case, close to) the given alpha level. The function generalizes Harding's (1984) algorithm to quickly generate the distribution.
Usage
cUmbrPK(alpha, n, peak=NA, method=NA, n.mc=10000)
Arguments
Value
Returns a list with "NSM3Ch6c" class containing the following components:nnumber of observations in the k data groupscutoff.Uupper tail cutoff at or below user-specified alphatrue.alpha.Utrue alpha level corresponding to cutoff.U (if method="Exact")
