Using sensitivity analysis to identify key factors for the propagation of a plant epidemic [PDF]
Royal Society Open Science, 2018 Identifying the key factors underlying the spread of a disease is an essential but challenging prerequisite to design management strategies. To tackle this issue, we propose an approach based on sensitivity analyses of a spatiotemporal stochastic model ...
