Math modeling can seem arcane, but I believe it is most effective when it incorporates intuitive or common-sense features. In describing the way people play the big jackpot games, for instance, we intuitively recognize that there are some people who play nearly all the time, and others who rush in when the jackpot gets to a certain size. I reassured Veronique’s agency that a well-crafted model can incorporate these features, in NASPL Insights August 2014.
