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

chiSq_gof(object, breaks, ...)

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

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

# S3 method for 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.

Value

data.frame

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).
