In this case, Y represents probability of death; MLDAXst is a binary indicator coded as one for subjects who were legally permitted to drink prior to age 21, and zero for those who were not. MLDAX is determined by state (s) and birth year (t), with β being the parameter of interest; namely, the log of the odds ratio for the association between exposure to MLDA<21 and death by suicide or homicide. For some analyses, we also included interactions between the state indicators (α) and birth-year coded as a continuous variable to account for unobserved state-level variables that may change over time.
