Global sensitivity analysis of the objective function G(θ). Partitioning of variance using Extended Fourier Amplitude Sampling Test (eFAST) on the objective function G(θ) that measured the agreement between the observed verotoxigenic Escherichia coli O157:H7 herd status in a longitudinal observational study from October 2009 to December 2012 (38 months) in 126 cattle herds and a stochastic disease spread model that replicated that study. The first-order (Si) sensitivity indexes (black bars) describes variance explained by the value assigned to that parameter. The total-order (STi) sensitivity indexes (grey bars) describes variance caused by this parameter and non-linear effects between this parameter and others. Error bars are standard error over three resample curves.
