摘要
目的 探讨疾病空间分布的量化统计指标在疾病空间分析中的应用价值。方法 在概率模型基础上 ,提出反应疾病空间分布状态的定量统计指标———病例聚集系数、病例平均密度、病例平均聚集度和病例聚灶指数。结果 获得疾病空间分布状态定量统计指标的计算方法和流行病学含义。结论 该统计指标不仅可分析疾病的空间分布特征 。
Objective to explore applicability of quantum statistical index in studying the spatial distibution of disease.Methods based on the probability models,the quantum statistical index on spatial distribution of disease-case concentrate coefficient(C),case density(m c),case cowding( c)and case aggregation index(A) were put forward.Results the quantum statistical index on the spatial distibution of disease and their epidemicology implication were obtained.Conclusion in studying the spatial distribution of disease,not only the feature on spatial distribution of disease,but also its epidemicology implication can be analyzed by using these quantum statistical index.
