A moving average would make sense, but cubic fit? WTF? In epidemiology, is there a theoretical basis for death rates to follow any type of polynomial trend with time? If you measure say, drag force vs. airspeed at finite intervals, sure, use a second-order fit. Drag varies with the square of speed, theory predicts that relation. But there isn't such for death rates, is there?
