摘要:

目的: 建立日本血吸虫病抽样调查居民感染率的误差分析和统计方法。方法: 按照多重分层、整群随机抽样的要求, 应用误差传递理论, 结合整群随机抽样和分层随机抽样标准误的计算公式, 对居民血吸虫感染率抽样误差进行统计分析和理论推导。结果: 得出流行省份及其不同类型未控制流行地区居民血吸虫感染率的抽样误差的4 个公式。结论: 推导并建立多重分层、整群随机抽样误差的计算公式。

Abstract:

AIM: To establish a set of statistic formulas on sampling error of infection rate of residents in sampling survey of schistosomiasis. METHODS: According to the requirement of multiple-stratifying and clustering random sampling, the sampling error of schistosome infection rate of residents was analysed through introducing the theory of error transferring and combining the calcu-lation formula of standard error in clustering random sampling and stratified random sampling. RESULTS: Four standard error formula of prevalence were introduced in different provinces and different types in endemic areas. CONCLUSION: The calculation formulas of multiple-stratifying and clustering random sampling are theoretically set up.
