结合历史与随机化对照评估比例趋势AI 解读

A statistical method for incorporating historical control data in the analysis of proportions is proposed and illustrated. The method has as its extremes logistic regressions completely pooling and completely ignoring historical controls. The degree of pooling used is determined by the variability from experiment to experiment in the control incidences. The fit of historical control groups to an assumed normal logistic model is assessed using probability plotting techniques.…

两种序列相关检验的稳健性性质AI 解读

We compare Geary's test based on the number of sign changes in residuals with the Durbin-Watson (DW) test for serial correlation. We derive the asymptotic distribution of Geary's statistic for the special case of identically distributed random variables and show that it is asymptotically distribution free for symmetric errors. Monte Carlo simulations show that the DW procedure is generally more powerful and robust than Geary's test.
