Abstract:

Suppose that items live their lives in a series of environments that change when the items reach known ages called change points. Modeling the survival function of such items over their entire lives, using a parametric survival function that has only a few parameters, may not provide an adequate fit to the survival function. We present a method of fitting the survival function, using a separate fit of the parameters of the survival function for each interval between change points. This allows the estimated survival function to take the changing environments into account. The effectiveness of this procedure is demonstrated. A comparison between this method and other methods is given.
