chiSq_gof {Countr} | 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 |

`breaks` |
integer values at which the breaks shoudl happen. The function
will compute the observed frequencies in the intervals |

`...` |
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
