Appendix A

This file contains a processed sample of simulated data and the results from their analysis.The structure of the contents is described below.<br>1. SimulationsFor each functional group, the dataset includes 5 simulations per simulation scenario.Included in the section "simulated_parameters_real_values":- Nitd: Total number of daily roadkills at site i, month t, day d.- NitD: Total number of roadkills during the maximum number of days a carcass remains visible in the survey area at site i and month t.- NtD: Total number of roadkills across all survey sites combined in month t.<br>Additionally, this section includes the true probability values of detection biases:- pL: Carcass location bias- pP: Carcass persistence bias- pOwalking: Carcass observation bias for walking surveys- pOcycling: Carcass observation bias for cycling surveys- pOdriving: Carcass observation bias for driving surveys<br>2. Bayesian Parameter EstimationIncluded in the section "Bayesian_parameter_estimation":- Posterior estimates for the following parameters: - totalN (NtD): Estimated total number of roadkills - pL - pP - pOwalking - pOcycling - pOdriving<br>Each parameter includes:- Posterior mean- R̂ (R-hat) convergence diagnostic- Full posterior distribution<br><br>
