SAS macro to generate randomized quantile residuals from PROC GLIMMIX?

quentinread — Tue, 02 Jun 2026 16:17:13 GMT

I am a big user of the R package DHARMa (https://cran.r-project.org/web/packages/DHARMa/vignettes/DHARMa.html) which produces scaled quantile residuals from fitted GLMMs and does a variety of diagnostic tests on them such as uniformity, overdispersion, and autocorrelation.

I know that it is possible to write a macro in SAS to generate quantile residuals via simulation from a fitted GLIMMIX model and run the diagnostic tests. But I was curious if anyone in the community already has a macro that can do that, that they are willing to share.

Thanks in advance for your help!

I'm not aware of any macro for producing "randomized quantile residuals" from fitted GLMs (GENMOD procedure) or GLMMs (GLIMMIX procedure).

It shouldn't be difficult to write such a macro ... and you can have a quick-start by asking

Claude Code CLI or
Open-AI Codex or
GitHub Copilot

to come up with a first version.

Also, you can submit R-code in your SAS program.
