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.
