Sensitivity analysis to test the robustness of the expert elicitation
In order to identify whether the ranking of COVID-19 drivers of emergence in pets was influenced or not by the choice of experts, a sensitivity analysis was performed.
First, we started by ranking the drivers using the obtained median OWSDri . Second, an expert was not considered in the analysis and the ranking of the drivers was done using the same methodology previously described. This was done expert by expert. Third, we counted how many changes in the ranking were observed, for each driver, only considering changes of more than five ranks (i.e. around 10% of all drivers). A graph was created to visualize any modification of rank induced by the withdrawal of a given expert.
