Estimation for Censored Exponential Data When the Censoring Times are Subject to Error
删失时间存在误差时指数分布删失数据的估计
SUMMARY The problem of estimating the parameter of the negative exponential distribution with censored data may be complicated by a lack of complete knowledge of the censoring times. The effect of ignoring these errors in the censoring times rather than using a complete maximum likelihood estimation approach is investigated and it is shown that the loss in efficiency is generally small for the inverted gamma model considered in this paper. The theory is supplemented by some…
