ABSTRACT
Balakrishnan et al. (2008) combined the last two schemes of sampling and introduced an unified hybrid censored sampling (UHCS). In this scheme, one prefixes k , r ∈ {1, 2, . . . , n} and T1, T2 ∈ (0, ∞) such that k < r and T1 < T2. If the kth failure occurs before time T1, the experiment terminates at min{max{Xr:n, T1}, T2}. If it occurs between T1 and T2, the experiment terminates at min{Xr:n, T2} and finally if it occurs after time T2, then the experiment is terminated at Xk:n. The unified HCS can guarantee that at least k failures can be observed.
