Figure 5.

Parameter relation obtained from the 2-combination parameter test. (a) When ${\sigma }_0=0$, $\mu$ and $Q_m$ are slightly correlated with the best fit values concentrated around $\mu =9.00\times {10}^{-3}$ and $Q_m=30$. (b) When ${\sigma }_0=5\%$, the relationship between $\mu$ and $Q_m$ is much clearer, leading to a larger ARE%.
