Dean's community mottling index, though a useful summary measure, suffers from the use of arbitrary scores and the inability to describe the frequency in each of the levels of mottling. An alternative statistical approach, based on the proportional odds model, is used here to describe the severity of mottling in a community. The use of this model is demonstrated on prevalence data collected on 16 Texas communities.
迪恩社区斑纹指数虽是一种有用的汇总指标，但存在评分随意以及无法描述各斑纹等级出现频率的问题。本文采用一种基于比例优势模型的替代统计方法来描述社区中斑纹的严重程度。该模型的应用通过在得克萨斯州16个社区收集的患病率数据得以展示。
