A Note on Generalized Inverses of Distribution Function and Quantile Transformation

In this paper we study the relations of four possible generalized inverses of a general distribution functions and their right-continuity properties. We correct a right-continuity result of the generalized inverse used in statistical literature. We also prove the validity of a new generalized inverse which is always right-continuous.

有效性试验、非劣效性试验、和等效试验之间的比较（英文）

概述:一种新型药物或治疗的效果通常是通过临床随机对照试验获得的。然而,假设的设定对生物医学研究者来说仍然是具有挑战性的问题。在本调查中,我们讨论了有效性试验、非劣效性试验、和等效性试验。这三类试验对治疗效果均有不同的假设。我们比较了这些试验中的假设并提供了样本量计算公式。
