Fig. 7 (Color online) The 1D marginalized probability distributions of $\Omega_{m0}$ by using $\chi^2$ statistics with constant $\alpha$, $\beta$ (red solid line) and Bayesian statistics with linear $\alpha$, $\beta$ (blue dashed line). We consider the CPL, JBP, BA and Wang models respectively, based on the combined JLA+CMB+GC data.
