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…
Robust Estimation in Step-Stress Experiments under Weibull Lifetime Distributions
María Jaenada, Juan Millán, Leandro Pardo
Many modern products are highly reliable, often exhibiting long lifetimes. As a result, conducting experiments under normal operating conditions can be prohibitively time-consuming…
Robust Estimation in Step-Stress Experiments under Exponential Lifetime Distributions
María Jaenada, Juan Manuel Millán, Leandro Pardo
Many modern products exhibit high reliability, often resulting in long times to failure. Consequently, conducting experiments under normal operating conditions may require an impra…
Robust statistical inference for accelerated life-tests with one-shot devices under log-logistic distributions
María González-Calderón, María Jaenada, Leandro Pardo
A one-shot device is a unit that operates only once, after which it is either destroyed or needs to be rebuilt. For this type of device, the operational status can only be assessed…
Robust Rao-type tests for step-stress accelerated life-tests under interval-monitoring and Weibull lifetime distributions
Narayanaswamy Balakrishnan, María Jaenada, Leandro Pardo
Many products in engineering are highly reliable with large mean lifetimes to failure. Performing lifetests under normal operations conditions would thus require long experimentati…
Robust inference for an interval-monitored step-stress experiment under proportional hazards
Narayanaswamy Balakrishnan, María Jaenada, Leandro Pardo
Accelerated life tests (ALTs) play a crucial role in reliability analyses, providing lifetime estimates of highly reliable products. Among ALTs, step-stress design increases the st…
Robust inference for an interval-monitored step-stress experiment with competing risks for failure
Narayanaswamy Balakrishnan, Maria Jaenada, Leandro Pardo
Accelerated life-tests (ALTs) are used for inferring lifetime characteristics of highly reliable products. In particular, step-stress ALTs increase the stress level at which units…
