It should also be noted that the Cox model is based on the assumption of a constant relative event rate (relative hazard) over the follow-up period: the "proportional hazards" assumption.
Their mean count, or piecewise constant event rate, can be evaluated by discrete probability distributions from the Poisson model family.
In this special case of a constant hazard, the event times are described as having an exponential distribution.
Mass shootings, on the other hand, are constant events.
