同时审核一组比赛
Auditing a collection of races simultaneously
摘要：
一次选举中的种族集合可以作为一个组进行审计，方法是审计一批选票的随机样本，并以特定的方式将这些批次中所代表的种族中观察到的差异结合起来：最大跨种族相对夸大成对差额（MARROP）。可以使用各种概率抽样方案，在基于选票的审计基础上建立对整个比赛集合的风险限制审计。该审计控制了全系列错误率（一个或多个错误结果无法通过全手计数纠正的机会），其成本可能低于独立审计控制每次比较错误率的成本。如果批次的抽取概率与MARROP（PPEB抽样）的界限成比例，则该方法特别有效。
英文摘要：
A collection of races in a single election can be audited as a group by auditing a random sample of batches of ballots and combining observed discrepancies in the races represented in those batches in a particular way: the maximum across-race relative overstatement of pairwise margins (MARROP). A risk-limiting audit for the entire collection of races can be built on this ballot-based auditing using a variety of probability sampling schemes. The audit controls the familywise error rate (the chance that one or more incorrect outcomes fails to be corrected by a full hand count) at a cost that can be lower than that of controlling the per-comparison error rate with independent audits. The approach is particularly efficient if batches are drawn with probability proportional to a bound on the MARROP (PPEB sampling).
