hnp-package: Half-Normal Plots with Simulation Envelopes
Description
Generates (half-)normal plots with simulation envelopes for common diagnostics from fitted models for a range of model classes. The function hnp() is written so that it is relatively easy to extend it to new model classes and different diagnostics that are not already implemented. A few example datasets are included. The main functions are hnp and plot.hnpDetails

Package includes two functions, hnp and plot.hnp, as well as seven data sets extracted from Demétrio{Demetrio} et al (2014).
Explanation on how to produce the half-normal plots with simulation envelopes can be found in Demétrio{Demetrio} and Hinde (1997) and on the hnp function documentation.
Data sets are based on entomology studies and the focus is on overdispersed data. Details on overdispersion models can be found in Hinde and Demétrio{Demetrio} (1998).References
