 In this case, we know that BIC does not improve much after 4 segment classes. Now, we will not have a look at the characteristics of the segment classes. We are going to plot the mean methylation value and the length of the segment as a scatter plot; the result of this plot is shown in Figure \@ref(fig:segplot).

 4. Microsatellite instability (MSI) is associated with hyper-mutated tumors. As seen in Figure \@ref(fig:momutationsHeatmap), one of the subtypes has tumors with significantly more mutations than the other. Which subtype is that? Which NMF factor is associated with that subtype? And which NMF factor is associated with MSI? [Difficulty: **Advanced**]
