Miscellanea. A note on the relation between two forms of linear rank statistics for right censored and grouped data
证明了右删失和分组数据下两种线性秩统计量的等价性，并在无结值情况下给出直观解释，对从事生存分析或非参数统计的研究者有参考价值。
We show that two forms of linear rank statistics for right censored and grouped data are equivalent. In the case of no tied value among uncensored observations, we provide some intuition about the equivalence.
