iwp.test.pvalue: 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)

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.

Arguments

r

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

n

the sample size.
