Fig. 6From: Moving beyond the classic difference-in-differences model: a simulation study comparing statistical methods for estimating effectiveness of state-level policiesType I error rates for the AR models for four different GLMs: (6a) linear (unweighted), (6b) log linear (unweighted), (6c) Poisson, and (6d) negative binomial. Horizontal line denotes the target Type I error rate value of 0.05Back to article page
