Rankings of expected utility criterion $\widehat{U}(\mathit{\xi })=K^{-1}{\sum }_{k=1}^K{\widehat{u}}_{LF}({\mathbf{z}}^{(k)},\mathit{\xi })$, where ${\widehat{u}}_{LF}({\mathbf{z}}^{(k)},\mathit{\xi })=1/{\widehat{\text{Var}}}_{\mathit{\xi }}(\mathit{\lambda }|{\mathbf{z}}^{(k)})$ is the ABC posterior precision utility of the range parameter, when the uniform prior $\mathit{\lambda }\sim U[2.5,17.5]$ is used: top ABC rejection method, bottom importance weight update method
