Scheffé 混合模型下方差分析与竞争秩检验的蒙特卡洛研究AI 解读

Monte Carlo estimates are obtained of the small sample power of the classical F test and three competing rank tests for detecting two forms of treatment shift alternatives. These results were computed under Scheffé's mixed model for the case of one observation per cell using several variance-covariance matrices. Some small sample null distributions, empirical efficiencies, and robustness computations are also given.
