Robust variance estimation for rate ratio parameter estimates from individually matched case-control data
个体匹配病例—对照数据中发生率比估计的稳健方差
The asymptotic variance and robust variance estimators of rate ratios estimated using conditional logistic regression from individually‐matched case‐control data are derived when the presumed proportional hazards model is misspecified. The robust variance estimators are easily computed using Schoenfeld residuals generated from standard partial likelihood estimation software for failure time data. Simulation studies indicate that the robust variance estimators perform well…
