Elimination of other outliers were done using EUI data. However, the histogram of EUI was not very informative due to outliers as excessive as 3 million, which is not even realistic for EUI . Therefore, log-eui was calculated, and its histogram was used to eliminate outliers in the data frame. The histogram of log-EUI is shown in Figure 2 before eliminating  +/- 1 standard deviation of the mean of the data (around 8.5% of the size of the data), and Figure 3 shows after elimination of the outliers, Figure 3 looks like a normal distribution.
