[Authors] Vilijandas Bagdonavicius, Mikhail S. Nikulin [Title] On Goodness-of-Fit in Accelerated Life Testing [AMS Subj-class] 60E15, 62F12, 62J99, 62P10 [Keywords] Accelerated life testing, additive accumulation of damages, chi-squared goodness-of-fit, power function, proportional hazards, Sedyakin's model, step-stress [Abstract] Goodness-of-fit test for the generalized Sedyakin's model is proposed when accelerated experiments are done under step-stresses. Various alternatives are considered. Power of the test against the approaching alternatives is investigated.
