新的V折交叉验证法提供了高效的统计推断替代方案

研究人员推出了一种新的统计方法——V折交叉验证法(V-fold jackknife),旨在为半参数推断提供一种计算高效且理论可靠的替代自举法(bootstrap)的方案。该方法仅需V次留一折重拟(leave-fold-out refits),并利用交叉验证法伪值(jackknife pseudo-values)的离散度来估计不确定性,无需影响函数(influence functions)。对于标准的渐近线性估计量,V折交叉验证法统计量收敛于t分布,可产生有效的置信区间。该方法还可扩展至广义估计量,并在模拟研究中证明了在平均处理效应(average treatment effects)、Kaplan-Meier生存曲线(Kaplan-Meier survival curves)和高度自适应套索剂量反应曲线(highly adaptive lasso dose-response curves)方面具有可靠的推断能力。 AI

影响 为机器学习背景下的统计推断提供了一种更高效、理论更扎实的方法。
