摘要翻译:
我们构造了一个正态均值问题中的鲁棒经验Bayes置信区间(EBCIs)。区间集中在通常的线性经验贝叶斯估计,但使用一个临界值考虑收缩。假设均值为正态分布(Morris,1983b)的参数EBCIs可能在违反这一假设时基本上隐藏。相反,我们的EBCIs控制覆盖不管均值分布,同时保持接近参数EBCIs的长度,当均值确实是高斯的。如果将方法视为固定的,我们的EBCIs有一个平均覆盖保证:对于每个方法,$N$EBCIs的覆盖概率平均至少为$1-\alpha$。我们的实证应用考虑了美国社区对代际流动性的影响。

英文摘要:
We construct robust empirical Bayes confidence intervals (EBCIs) in a normal means problem. The intervals are centered at the usual linear empirical Bayes estimator, but use a critical value accounting for shrinkage. Parametric EBCIs that assume a normal distribution for the means (Morris, 1983b) may substantially undercover when this assumption is violated. In contrast, our EBCIs control coverage regardless of the means distribution, while remaining close in length to the parametric EBCIs when the means are indeed Gaussian. If the means are treated as fixed, our EBCIs have an average coverage guarantee: the coverage probability is at least $1 - \alpha$ on average across the $n$ EBCIs for each of the means. Our empirical application considers the effects of U.S. neighborhoods on intergenerational mobility.
