R Documentation

Formal Chi-square goodness-of-fit test

Description

Carry out the formal chi-square goodness-of-fit test described by Cameron (2013).

Usage

chiSq_gof(object, breaks, ...)

## S3 method for class 'renewal'
chiSq_gof(object, breaks, ...)

## S3 method for class 'negbin'
chiSq_gof(object, breaks, ...)

## S3 method for class 'glm'
chiSq_gof(object, breaks, ...)

Arguments

`object`	an object from class `renewal`.
`breaks`	integer values at which the breaks shoudl happen. The function will compute the observed frequencies in the intervals `[breaks[i], breaks[i + 1])`.
`...`	currently not used.

Details

The test is a conditional moment test described in details in Cameron (2013, Section 5.3.4). We compute the asymptotically equivalent outer product of the gradient version which is justified for renewal models (fully parametric + parameters based on MLE).

Value

data.frame
