    Inference of improved adaptive progressively censored competing risks data for Weibull lifetime models

    Recently, an improved adaptive Type-II progressive censoring scheme is proposed to ensure that the experimental time will not pass a pre-fixed time and ends the test after recording a pre-fixed number of failu...
