    • An example involves determining a missing-audience factor based on first impressions corresponding to first client devices that do not have database proprietor (DP) identifiers for use by a DP to identify subscribers registered with the DP, and based on second impressions corresponding to second client devices that do have the DP identifiers used by the DP to identify subscribers registered with the DP. The first impressions represent accesses to media via the first client devices. The second impressions represent access to the media via the second client devices. The example involves determining a coverage-corrected unique audience (CCUA) size based on the missing-audience factor and a UA size of DP subscribers exposed to the media. The UA size is determined based on impressions logged by the DP. The CCUA size corresponds to impressions logged by the DP and not logged by the DP.
    • 一个示例涉及基于与没有数据库所有者(DP)标识符的第一客户端设备相对应的第一印象来确定缺少受众因素,以供DP使用以识别向DP注册的订户,并且基于对应于第二客户端的第二印象 确实具有由DP使用的DP标识符来识别在DP上注册的用户的设备。 第一印象表示通过第一个客户端设备访问媒体。 第二次展示代表通过第二个客户端设备访问媒体。 该示例涉及基于丢失的受众因素和暴露于媒体的DP订户的UA大小来确定覆盖率校正的唯一受众(CCUA)大小。 UA大小根据DP记录的印象确定。 CCUA大小对应于DP记录的展示次数,而DP不记录。
