Degradation Platform Overview
In reliability analyses, the primary objective is to model the failure times of the product under study. In many situations, these failures occur because the product degrades (weakens) over time. But, sometimes failures do not occur. In these situations, modeling the product degradation over time is helpful in making predictions about failure times.
The Degradation platform can model data that follows linear or nonlinear degradation paths. If a path is nonlinear, transformations are available to linearize the path. If linearization is not possible, you can specify a nonlinear model.
You can also use the Degradation platform to perform stability analysis. Three types of linear models are fit, and an expiration date ...
