Asymptotic Efficiency of General Noniterative Estimators of Common Relative Risk
本文提出并证明了一个关于加权非迭代点估计量渐近有效性的定理，并改进了基于对数正态性的区间估计方法，对处理多个2×2表格的共同相对风险估计有用。
Gart (1962) presented consistent and efficient estimators of the common relative risk for several 2 × 2 tables, together with their associated confidences intervals. A theorem on the asymptotic efficiency of general, weighted noniterative point estimators is formulated and proved. A modification of interval estimators based on log normality is given.
