Accordingly, the above discussion points out that an MCI score is useful when applied to large datasets: it can provide the average score across all the records as well as the distribution of the scores across the records. To demonstrate this, we plot the distribution of the MCI scores across the HMP and GEBA datasets, for each of their corresponding records. As shown on Figure 3, this distribution reveals that the HMP dataset has indeed a larger number of records that currently are characterized with lower MCI score, compared to the GEBA dataset.
