iwp.test.pvalue: The p-value for the inverse Weibullness Test

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

The p-value for the inverse Weibullness Test

Description

Calculates the p-value for the inverse Weibullness test which is based on the sample correlation from the inverse Weibull plot.

Usage

iwp.test.pvalue(r, n)

Arguments

r	the sample correlation coefficient from the Weibull plot; r is in (0,1).
n	the sample size.

Details

The p-value for the inverse Weibullness test which is based on the sample correlation from the inverse Weibull plot. There is print method for class "htest".

Value

A list with class "htest" containing the following components:

statistic	the value of the test statistic (sample correlation from the Weibull plot)
p.value	the p-value for the test.
method	a character string indicating the inverse Weibullness test.
