中文简介: | 我们提出了三面检验,一个同时检验临床试验中的劣效、等效性和优越性的检验框架,用划分原则控制多个检验。与通常的双面测试方法一样,这种方法在两种处理中是完全对称的。然而,由于单侧检验检验了自卑和优越性的假设,该方法比单侧检验具有更大的自卑或不优越性。应用于经典的点零等价假设的三边检验方法表明,即使零等价假设本身不能被拒绝,有时也有可能对相关参数的符号进行推理。探讨了与置信区间的关系,并在最近的一些临床试验中证明了三边检验方法的有效性。 |
课程简介: | We propose three-sided testing, a testing framework for simultaneous testing of inferiority, equivalence and superiority in clinical trials, controlling for multiple testing using the partitioning principle. Like the usual two-sided testing approach, this approach is completely symmetric in the two treatments compared. Still, because the hypotheses of inferiority and superiority are tested with one-sided tests, the proposed approach has more power than the two-sided approach to infer non-inferiority or non-superiority. Applied to the classical point null hypothesis of equivalence, the three sided testing approach shows that it is sometimes possible to make an inference on the sign of the parameter of interest, even when the null hypothesis itself could not be rejected. Relationships with confidence intervals are explored, and the effectiveness of the three-sided testing approach is demonstrated in a number of recent clinical trials. |
