Sensitivity analysis. A Sensitivity analysis of the log likelihood as a function of infection parameters. The Z scale is minus the log of the likelihood, subtracted by the minimal cost which is the maximal likelihood. The x and y axes are the coefficient of the bacterial load in the infectivity term (α) and the power of the bacterial load in the infectivity term (γ). The optimal likelihood is indeed a minimum. B Sensitivity analysis as a function of infection parameters. The Z scale is minus the log of the likelihood, subtracted by the minimal cost which is the maximal likelihood. The x and y axes are the coefficient of the direct transmission term (β) and the constant infectivity term (δ). The optimal likelihood is indeed a minimum.
