On the Relative Efficiency of Grouped and Censored Survival Data
研究了分组生存数据中，删失实验相对于非删失实验在推断上的相对效率，假设观测随机右删失，也考虑了固定删失情形。
The relative efficiency of a censored experiment compared with the corresponding noncensored experiment for inference is examined for grouped survival data. It is assumed that observations are randomly right-censored. The case of fixed censoring is also considered.
