Check model goodness-of-fit

Source: R/gof.R, R/occu.R, R/pcount.R

Goodness-of-fit tests for ubmsFit models using posterior predictive checks

gof(object, draws = NULL, ...)

# S4 method for class 'ubmsFitOccu'
gof(object, draws = NULL, quiet = FALSE, ...)

# S4 method for class 'ubmsFitAbun'
gof(object, draws = NULL, quiet = FALSE, ...)

Arguments

object

A fitted model of class ubmsFit

draws

Number of draws from the posterior to use in the check

...

Currently ignored

quiet

If TRUE, suppress progress bar

Value

An object of class ubmsGOF containing statistics calculated from the posterior predictive distribution.

Functions

  • gof(ubmsFitOccu): Applies the MacKenzie-Bailey chi-square goodness of fit test for ocupancy models (MacKenzie and Bailey 2004).

  • gof(ubmsFitAbun): A goodness-of-fit test for N-mixture type models based on Pearson's chi-square.
