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.
