Accelerated testing is increasingly important to assure
product reliability with reduced development time. Reliability predictions are sensitive
to the accelerated life model selected. This presentation discusses principles for model
selection. Using the fact that the Eyring, Arrhenius and Inverse Power Law models are
nested special cases of a more general model, this session will present a statistical
test, using existing ReliaSoft software for model selection among them. Simulation
results will illustrate the power of the test, and we will discuss an example.
Key Words: Eyring, Arrhenius, Inverse Power Law, Model Selection, ALTA
