The file “apt.txt” contains data on rodent infestation in a sample of New York City apartments. See “rodents.doc” for a description of the dataset.
(a) Write the notation for a varying-intercept multilevel logistic regression (with community districts as the groups) for the probability of rodent infestation using the
individual-level predictors but no group-level predictors.
(b) The file “dist.txt” contains data on the 55 “community districts” (neighborhoods) in the city. Expand the model in part (a) by including the variables in “dist.txt” as group-level predictors.
