Supplement 2. R code of the simulation study presented in Appendix A.

File List ConvergenceIssues.r (MD5: c579e3efb69ab080a2263e919563c7a3) SimulationStudy.r (MD5: 0389b50a5ef371d0e9e6957357656345) Description The file SimulationStudy.r contains all the necessary code to run the simulation study in R. The different parmaters and variables are explained and defined in the script. The file ConvergenceIssues.r can be used as a demonstration of how, in presence of data from the Observation Confirmation Design, estimates from the Site Confirmation model do not always converge to the true (known) values. Convergence from the Observation Confirmation is much better. You can change the simulated ('true') values to assess how the convergence properties change.

说明：
文件`SimulationStudy.r`包含了在R语言环境中执行本次模拟研究所需的全部代码，脚本内对各类参数与变量进行了解释与定义。
文件`ConvergenceIssues.r`可用于演示：当使用观测确认设计（Observation Confirmation Design）生成的数据时，站点确认模型（Site Confirmation model）得到的估计结果并非总能收敛至真实（已知）数值；而基于观测确认设计的收敛效果则显著更优。用户可修改模拟得到的（"true"）数值，以评估收敛特性的变化规律。
