基于捕获-再捕获模型的双系统估计量模型式框架

摘要

用来估计人口总体真实人口数目的双系统估计量建立在捕获一再捕获模型基础上．这里的双系统指构造的估计量要同时用到普查资料系统和再普查资料系统．双系统估计量有I型和Ⅱ型2种形式．I型双系统估计量是其基本形式，构造较为简单．Ⅱ型双系统估计量充分考虑了普查与再普查之间发生的人口迁移，构造比较复杂，是其高级形式．%Dual System Estimator based on capture-recapture model is used to estimate the true popula-tion number for population. Here dual systems include census system and second census system that will be used to construct dual system estimator. It has type I and type II. Type I is its basic form with a rela- tively simple configuration. Type II, with its complex construction, takes full account of the migration ofpopulation between census and the second census, and is the advanced form of the dual system estimator.
