“…proposed an extended Weibull distribution having various shapes of hazard rates as constant, decreasing, increasing, unimodal and bathtub shape. Motivated by the applicability of Weibull distribution and a more realistic scenario in the study of partially observed competing risks data (see, for example, Ashour and Nassar
21 and Chacko and Mohan
22 ), this paper aims to derive statistical inferences under UHCS when the latent failure times follow Weibull distributions with partially observed failure causes. It is assumed that the latent failure times follow Weibull distributions with different scale parameters

and a common shape parameter
