test.HK1 {gofIG}R Documentation

The first Henze-Klar goodness-of-fit test for the inverse Gaussian family

Description

This function computes the goodness-of-fit test for the inverse Gaussian family due to Henze and Klar (2002).

Usage

test.HK1(data, a = 0, B = 500)

Arguments

data

a vector of positive numbers.

a

positive tuning parameter.

B

number of bootstrap iterations used to obtain p value.

Details

The test statistics is a weighted integral over the squared modulus of some measure of deviation of the empirical distribution of given data from the family of inverse Gaussian laws, expressed by means of the empirical Laplace transform.

Value

a list containing the value of the name of the test statistic, the used tuning parameter, the parameter estimation method, the value of the test statistic, the bootstrap p value, the values of the estimators, and the number of bootstrap iterations:

$Test

the name of the used test statistic.

$parameter

the value of the tuning parameter.

$T.value

the value of the test statistic.

$p.value

the approximated p value.

$par.est

the estimated parameters.

$boot.run

number of bootstrap iterations.
