[Correspondence] Gun violence prevention – Authors’ reply

We thank all authors for their interest in our paper;1 four main critiques are raised. First, Schell and Morral suggest that bootstrapping to recalculate standard error and confidence intervals would be appropriate in this context. We disagree. Bootstrapping is more appropriate under the assumption that observations are from an independent and identically distributed proportion. We are studying a highly interdependent set of populations, and fewer assumptions imposed on the data seem far more appropriate.
