Example of goodness of fit analysis and resulting inference.

Model Y χ2CI, N-m Critical * χ2CI, N-m p-value * Conclusion
Exponential 119.49 23.68 0 Exponential model does not show a good fit to the data
Beta poisson 6.56 22.36 0.92 Beta poisson shows a good fit to the data
*

Ho: The model is a good fit to the data – if not using p-value: Y < χ2CI, N-m critical value to fail to reject.
