Robust tests for log-normal lifetimes under cyclic-stress accelerated tests and interval monitoring
María Jaenada, Leandro Pardo, Kiran Prajapat
Some products are, by nature, designed to operate under stress conditions that repeatedly cycle between two levels, such as batteries undergoing repeated charge and discharge, or c…
Robust inference for cyclic-stress accelerated life tests under interval monitoring with lognormal lifetimes
María Jaenada, Leandro Pardo, Kiran Prajapat
Highly reliable products are often tested under accelerated conditions to provoke failures within a feasible timeframe. For products whose service life involves repeated alternatio…
A Finite Mixture Failure-rate based Heterogeneous Step-stress Accelerated Life Testing (h-SSALT) Model
Pranoy Palit, Ayan Pal, Kiran Prajapat
Traditional step-stress accelerated life testing models assume that test units originate from a homogeneous population. Recently, Lu and Kateri (2025) proposed a heterogeneous cumu…
Exact Bayesian Planning for Simple Step-Stress Accelerated Life Testing with Competing Risks
Kiran Prajapat
We propose a Bayesian framework for planning simple step-stress accelerated life tests when items are subject to two independent competing failure modes We assume that the competin…
Estimation Method under Three-Parameter Generalized Exponential Model: Consistency, Uniqueness and its Applications
Kiran Prajapat, Sharmishtha Mitra, Debasis Kundu
In numerous instances, the generalized exponential distribution can be used as an alternative to the most widely used non-regular family of distributions: Weibull, gamma, lognormal…
