Optimal Step-Stress Test Under Progressive Type-I Censoring

Summary & Conclusions—We consider in this work a k-step-stress accelerated test with equal duration steps τ. Censoring is allowed at each change stress point iτ, i=1,‥․,k. The problem of choosing the optimal τ is addressed using variance-optimality as well as determinant-optimality criteria. We investigate in detail the case of progressively Type-I right censored data with a single stress variable.
