CIV-GLMM-diagnostics

What's this?

This repository contains the R code and .qmd files used to generate the plots and numerical results, via simulation, presented in the article:

Ángel, J. A.; Vélez, J.I. (2026). Finite-Sample Diagnostics for Random-Effects Misspecification in Poisson Generalized Linear Mixed Models. Mathematics 2026, 14(12), 2042;2026.

About the files

Numerical experiments

The files:

• simulations_CIV_M0.R
• simulations_CIV_M1.R
• simulations_CIV_M2.R

correspond to the instructions required to simulate the scenarios and estimate the empirical probability of Type I error and Power for the CIV test.

To run them, use the following instructions from the terminal:

cd ~/path/to/file/
Rscript simulations_CIV_M0.R
Rscript simulations_CIV_M1.R
Rscript simulations_CIV_M2.R

The file

• civ_white_simulation_src.R

contains the R code to compare the CIV test and White's version. The results are presented in Table 1 of the article.

To run it, use the following from the terminal:

cd ~/path/to/file/
Rscript civ_white_simulation_src.R

Figures

The figures reported in the article can be reproduced through the following files:

• figures_1_2.qmd
• figures_3_4_5.qmd

Simply download them, open them in RStudio or Positron, and render the document.
