A Nice Technical, from Steve Ellison
I was discussing the Weibull distribution, the classic bathtub distribution, with a colleague this week in the context of time to failure of computer hardware. He pointed out that the Weibull distribution is really a combination of two distributions, a distribution of the weak (high "infant mortality") and a distribution of the strong (in which wearing out from old age is the primary culprit). This is an interesting insight that might have applications in our field.
