On Relative Risk Estimation Under Multiple Matching
针对回顾性研究中罕见病多重匹配设计，提出一种新的非迭代估计量，通过平均单元格比值比的对数来估计相对风险。
The estimation of relative risk from a rare disease in a retrospective design with multiple matching is investigated. This paper proposes a new noniterative estimator by averaging the logarithms of cell odds ratios.
