LRI.test {EWGoF}

GoF tests based on the Laplace transform, the mean residual life and the integrated distribution function for the Exponential distribution

Description

Computes the Weibull GoF tests based on the Laplace transform: Baringhaus-Henze (BH) and Henze (He). The test statistic of Klar (Kl) is based on the integrated distribution function. Two tests are based on the mean residual life (BHC, BHK).

Usage

LRI.test(x, type = "BH", a = 1, nsim = 200)

Arguments

x

a numeric vector of data values.

type

the type of the test statistic used. "BH" is the default used test of Baringhaus-Henze,"He" for Henze, "Kl" for Klar, "BHC" and "BHK" for the tests based on the integrated distribution function.

a

parameter value to be adjusted for the test statistics.

nsim

an integer specifying the number of replicates used in Monte Carlo.

Value

An object of class htest.
