gofCopula (version 0.3-1)

gofGetHybrid: GetHybrid gof test

Description

gofGetHybrid computes based on previous test results from this package and on p-values from your own goodness-of-fit tests the hybrid test p-values for the specified testing size.

Usage

gofGetHybrid(result, p_values = NULL, nsets = NULL)

Arguments

result

An object of class gofCOP.

p_values

A vector containing different p-values from your own goodness-of-fit tests. If the elements are unnamed, the test results in the output will be labeled with Test_A, Test_B etc.

nsets

The desired number of tests to be included in each hybrid test. It should be an integer larger than 1 and smaller or equal than the number of tests given in result and p_values together. If nsets is set NULL (default), all possible testing sizes are calculated.

Value

An object of the class gofCOP with the components

method

a character which informs about the performed analysis

copula

the copula tested for

margins

the method used to estimate the margin distribution.

param.margins

the parameters of the estimated margin distributions. Only applicable if the margins were not specified as "ranks" or NULL.

theta

dependence parameters of the copulae

df

the degrees of freedem of the copula. Only applicable for t-copula.

res.tests

a matrix with the p-values and test statistics of the hybrid and the individual tests
