Rank Tests for Censored Randomized Block Designs
针对随机区组实验中存在右删失数据的情况，提出了秩检验方法，并证明其是Friedman检验和Brown-Mood检验在删失数据下的推广，适用于生存分析等问题。
Rank tests are proposed and studied for the hypothesis of equal treatment effects in randomized block experiments. The procedures are applicable to samples containing arbitrarily right-censored observations as well as uncensored observations. In the case of logistic and double exponential rank scores, the tests are shown to be censored data extensions of the well-known Friedman (1937) and Brown & Mood (1951) procedures respectively. The application of the techniques to problems in survival analysis is also discussed.
