Poisson Regression for Counts & Rates – Practice Quiz

Model event counts and exposure-adjusted rates with Poisson regression. Calculate predictions, rate ratios, exposure offsets, likelihood contributions and deviance comparisons using original service, infrastructure and operations scenarios. Prerequisites: GLMs, Poisson distributions, logarithms and likelihood inference. Analytical challenges address units, aggregation, zero exposure, conditional assumptions and the limits of causal interpretation.
