According to the analysis above, we could suggest that the commonality of the scenario based on DRAM-MCMC is better than that based on MCMC. In order to prove the availability of the scenario, we performed an analysis based on the data and obtained the mean and the standard deviation of relative error, as listed in Table 3. This shows that for the 80th quantile, the mean and the standard deviation of the relative errors are all less than 20%, relatively small, and the 90 quantile of the relative errors are all less than 31.18%.
