diagn

This function computes case-level diagnostics for generalized linear models. Conditional on model type, the function computes the most relevant diagnostics (circa 2024) and returns them as a data.frame object.

For example:

library(catregs)
data("Mize19AH")
m1 <- glm(alcB ~woman*parrole + age + race2 + race3 + race4 + income + ed1 + ed2 + ed3 + ed4,family="binomial",data=Mize19AH)
head(diagn(m1))
