| Abstract: |
| 1949-2008年我国累计登记麻风患者48万余例,主要分布在北纬38°以南的东南沿海和长江流域省份.新中国成立后,经过积极防治,至20世纪80年代初,以氨苯砜单疗治愈的患者达31万余例;1986年在全国普遍推广WHO联合化疗方案,至2008年底全国累计接受联合化疗的麻风患者近8万例. |
| English Abstract: |
| Multistage sampling techniques are widely applied in the cross-sectional study of epidemiology, while methods based on independent assumption are still used to analyze such complex survey data. This paper aims to introduce the application of weighted estimation methods for the complex survey data. A brief overview of basic theory is described, and then a practical analysis is illustrated to apply to the weighted estimation algorithm in a stratified two-stage clustered sampling data. For multistage sampling survey data, weighted estimation method can be used to obtain unbiased point estimation and more reasonable variance estimation, and so make proper statistical inference by correcting the clustering, stratification and unequal probability effects. |
