Sparse capture-recapture data from open populations are difficult to analyze using currently available frequentist statistical methods. However, in closed capture-recapture experiments, the Chao sparse estimator (Chao, 1989, Biometrics 45, 427-438) may be used to estimate population sizes when there are few recaptures. Here, we extend the Chao (1989) closed population size estimator to the open population setting by using linear regression and extrapolation techniques. We conduct a small simulation study and apply the models to several sparse capture-recapture data sets.
使用当前可用的频率统计方法来分析开放种群的稀疏捕获-再捕获数据是很困难的。然而，在封闭的捕获-再捕获实验中，当再捕获次数较少时，Chao稀疏估计器（Chao，1989年，《生物统计学》45卷，427 - 438页）可用于估计种群大小。在此，我们通过使用线性回归和外推技术，将Chao（1989年）的封闭种群大小估计器扩展到开放种群的情形。我们进行了一项小型模拟研究，并将这些模型应用于几个稀疏捕获-再捕获数据集。
