5. ### GLM with multiple categorical predictors

Hello internet, lets say I want to predict an outcome using multiple categorical predictors. Please consider the follow reproducible R-code: library(dplyr) library(psych) set.seed(42) n <- 500 df <- data.frame( loneliness = round(runif(n, 0, 1)), pet = factor(round(runif(n, 0, 1)))...
