基于双记录系统的种群规模估计:轮廓-似然法

On the Population Size Estimation from Dual-record System: Profile-Likelihood Approaches

Kiranmoy Chatterjee, Diganta Mukherjee

摘要:

基于各种应用的需要,我们考虑了双记录系统(DRS)(等价于两样本捕获-再捕获实验)中的齐次人口规模(N)估计问题。独立捕获-再捕获模型Mt的似然估计在这种情况下被广泛使用,尽管行为依赖模型Mtb的适当性得到一致认可。我们的主要目的是调查使用几个相关的伪似然方法剖析N,明确的模型Mtb。提出了一种调整轮廓似然的方法。通过与Lee等人(Statistica Sinica,2003,vol.13)提出的一般捕获-再捕获实验的贝叶斯估计进行比较,对所提方法的性能进行了仿真研究。我们还分析了可能的模型误指定的影响,由于使用模型山,在效率和鲁棒性。最后,两个现实生活中的例子,具有不同的特点,说明所讨论的方法。

英文摘要:

Motivated by various applications, we consider the problem of homogeneous human population size (N) estimation from Dual-record system (DRS) (equivalently, two-sample capture-recapture experiment). The likelihood estimate from the independent capture-recapture model Mt is widely used in this context though appropriateness of the behavioral dependence model Mtb is unanimously acknowledged. Our primary aim is to investigate the use of several relevant pseudo-likelihood methods profiling N, explicitly for model Mtb. An adjustment over profile likelihood is proposed. Simulation studies are carried out to evaluate the performance of the proposed method compared with Bayes estimate suggested for general capture-recapture experiment by Lee et al. (Statistica Sinica, 2003, vol. 13). We also analyse the effect of possible model mis-specification, due to the use of model Mt, in terms of efficiency and robustness. Finally two real life examples with different characteristics are presented for illustration of the methodologies discussed.
