论文摘要
Tang得出了在优越性，非劣势和等效试验中进行T检验和协方差分析（ANCOVA）的确切功率公式。可以通过使用Owen的Q函数来简化等效试验中的功率计算，该功能可在标准统计软件中使用。我们将ANCOVA的确切功率确定方法扩展到未分层和分层的多臂随机试验。该方法应用于多臂试验和金标准非劣效试验的设计。
Tang derived the exact power formulae for t tests and analysis of covariance (ANCOVA) in superiority, noninferiority and equivalence trials. The power calculation in equivalence trials can be simplified by using Owen's Q function, which is available in standard statistical software. We extend the exact power determination method for ANCOVA to unstratified and stratified multi-arm randomized trials. The method is applied to the design of multi-arm trials and gold standard noninferiority trials.
