Bayesian Testing Procedure on the Lifetime Performance Index of Products Following Chen Lifetime Distribution Based on the Progressive Type-II Censored Sample

Shu-Fei Wu, Wei-Tsung Chang
2021 Symmetry  
We derived the uniformly minimum variance unbiased estimator (UMVUE) for CL, and we used this estimator to develop a hypothesis testing procedure of CL under a lower specification limit based on the progressive  ...  With the high demands on the quality of high-tech products for consumers, assuring the lifetime performance is a very important task for competitive manufacturing industries.  ...  [14] evaluated the lifetime performance index for products with the Burr XII distribution. Lee [15] assessed the lifetime performance index of Rayleigh products based on the Bayesian estimation.  ...

Assessing the Lifetime Performance Index of Burr Type III Distribution under Progressive Type II Censoring

Amal Hassan, Salwa Assar, Amany Selmy
2021 Pakistan Journal of Statistics and Operation Research  
In the present study, we construct a maximum likelihood estimator of CL under Burr Type III distribution based on the progressive Type II censored sample.  ...  Hence, lifetime performance index CL is used to measure the potential and performance of a process.  ...  For instance, Lee et al. (2009) proposed a hypothesis testing procedure based on the ML estimator of CL to evaluate the product quality for two-parameter exponential under PTIIC samples.  ...
