In NSM3: Functions and Datasets to Accompany Hollander, Wolfe, and Chicken - Nonparametric Statistical Methods, Third Edition

Computes a critical value for the Mack-Skillings MS distribution.

Description

This function computes the critical value for the Mack-Skillings MS distribution at (or typically in the "Exact" and "Monte Carlo" cases, close to) the given alpha level.

Usage

cMackSkil(alpha,k,n,c, method=NA, n.mc=10000)

Arguments

alpha	A numeric value between 0 and 1.
k	A numeric value indicating the number of treatments.
n	A numeric value indicating the number of blocks.
c	A numeric value indicating the number of replications for each treatment-block combination.
method	Either "Exact", "Monte Carlo" or "Asymptotic", indicating the desired distribution. When method=NA, "Exact" will be used if the number of permutations is 10,000 or less. Otherwise, "Monte Carlo" will be used.
n.mc	If method="Monte Carlo", the number of Monte Carlo samples used to estimate the distribution. Otherwise, not used.

Value

Returns a list with "NSM3Ch7c" class containing the following components:

k	number of treatments
n	number of blocks
c	number of replications
cutoff.U	upper tail cutoff at or below user-specified alpha
true.alpha.U	true alpha level corresponding to cutoff.U (if method="Exact")
