The following equation shows the form of our outcome model.
Let
ARit = 1 if offender i was arrested during time t and 0 otherwise
DCi = 1 if offender i was a drug court participant and 0 otherwise
TimeTit = 1 if the observation is at time T = t and 0 otherwise
Zit = a vector of covariates
εit = error term
Then
ARit = β0 + β1DCi + β2Time1it + β3Time3it + β4Time4it + β5Time5it + β6Time6it + β7DCi * Time7it + β8DCi * Time1it + β9DCi * Time3it + β10DCi * Time4it + β11DCi * Time5it + β12DCi * Time6it + β13DCi * Time7it + γZit + εit
