wp.test.critical: Critical Value for the Weibullness Test

In weibullness: Goodness-of-Fit Test for Weibull Distribution (Weibullness)

Critical Value for the Weibullness Test

Description

Calculates the critical value for the Weibullness test

Usage

wp.test.critical(alpha, n)

Arguments

alpha	the significance level.
n	the sample size.

Details

This function calculates the critical value for the Weibullness test which is constructed using the sample correlation from the associated Weibull plot. The critical value is then looked up in Weibull.Plot.Quantiles. There is print method for class "wp.test.critical".

Value

A list with class "wp.test.critical" containing the following components:

sample.size	sample size (missing observations are deleted).
alpha	significance level.
critical.value	critical value.
data.name	a character string giving the name(s) of the data.
