经典频率学随机效应模型可通过 Q 检验获得研究间方差的矩估计,但是无法获得研究间协方差的 95% 可信区间(confidence interval,CI),而且基于频率学的 Meta 分析检验效能较低。在传统的 Meta 分析模型中,效应量指标的分布一般假设服从正态分布。例如,对于二分类资料的 Meta 分析而言,最常用的效应量为比值比(odds ...
Estimation of median survival time and its 95% confidence interval using SAS PROC LIFETESTABSTRACTPaul A. Talsma
since SAS 9.2, the default CONFTYPE=LOGLOG in proc lifetest. if I want calculate BrookMeyer-Crowley confidence interval for the medial survival, must I set CONFTYPE = LINEAR? How do I know the confidence interval I got is Brookmeyer-Crowley CI? 0 Likes 1...
One such case is, computing theconfidence interval for responders using binomial proportion. In many situations it is possible that the data do not contain any responders, however, the summary table still needs the confidence interval forresponder.Does PROC FREQ calculate the confidence interval for ...
Placing a confidence interval on the intercept would be nicely informative. 0 Likes Reply Kai1989 Fluorite | Level 6 Re: Proc Mixed for animal preference study (can't even tell what kind of the experimental design it Posted 02-15-2017 12:35 AM (4254 views) ...
