Table 3 Sensitivity of \(\mathcal{R}_{2}^{*}\). A positive sign \((+)\) means that the curve of the parameter toward \(\mathcal{R}_{2}^{*}\) is monotonically increasing, so a larger parameter value will lead to greater \(\mathcal{R}_{2}^{*}\). Meanwhile, a negative sign \((-)\) means the exact opposite
