Abstract:

Various hybrid censoring schemes, a mixture of Type I and II censoring schemes, have been suggested to control both efficiency and termination time. In this paper, we consider a general hybrid censoring scheme as a censoring scheme with lower and upper censoring bounds, which incorporates current hybrid censoring schemes. The generalized Type I hybrid censoring, for example, is a special case of the general hybrid censoring scheme where a predetermined censoring time (Type I censoring) is given and the lower and upper censoring bounds are given as numbers of failures (Type II bounds). We even extend the censoring time and censoring bounds to be hybrid bounds and show that the current unified hybrid censoring scheme is also a special case of the general hybrid censoring scheme. We provides some interesting statistical results for this general hybrid censoring scheme.
