对于右删失数据，最常用的检验可能是加权logrank检验，例如logrank和Wilcoxon类型的检验。本文回顾了区间删失数据加权对数检验的几个推广，并提出了一个R包Interval来实现其中的许多。区间包依赖于PERM包，PERM包执行精确和渐近的线性置换测试。PERM包执行已有的硬币包中包括的许多测试，并提供硬币的独立验证。我们回顾了区间删失数据的分析方法，并描述和展示了如何使用区间和PERM包。
For right-censored data perhaps the most commonly used tests are weighted logrank tests, such as the logrank and Wilcoxon-type tests. In this paper we review several generalizations of those weighted logrank tests to interval-censored data and present an R package, interval, to implement many of them. The interval package depends on the perm package, also presented here, which performs exact and asymptotic linear permutation tests. The perm package performs many of the tests included in the already available coin package, and provides an independent validation of coin. We review analysis methods for interval-censored data, and we describe and show how to use the interval and perm packages.
