Diagnostics for HierArchical Regession Models

Via email: I have two models, and I created the diagnostic plots for them using the Dharma package and the simulateResiduals() function. There seem to be a couple of significant...
Request via email for a pdf version of the vignette. Theoretically, it should be possible to do this automatically, see - https://stackoverflow.com/questions/31214524/how-do-i-produce-r-package-vignettes-in-multiple-formats - https://community.rstudio.com/t/html-and-pdf-vignette-reasonable/132749 But I'm not sure if it's...
Hi @florianhartig When using recalculateResiduals, the output gives the scaled residuals but not the corresponding groups (time in my case). This might cause confusion because I think the aggregate function...

Via email: [...] I have a qqplot with pearson residuals from a poisson GLM that doesnt look so good (in attachment), and a Kolmorov-Smirnoff test indicated sig non linear distribution....
Hi, I am pretty new to DHARMa and GLMM model diagnosis using this new framework. First of all, I want to thank you for the development of the package and...
Hello Florian, It's the first time I use DHARMA as a diagnostic tool and I went through the tutorial and some previous issues (eg. #181) but I am still not...
I have been trying to perform beta regression modeling with random effects. I have sex ratio as the response variable, and climatic variables + years (1970-2021) as predictor variables. Different...
