Comparison of tests of linear regression assumptions across the distribution of DNA methylation levels. Boxplots of –log10(p-value) for each of the 5 tests (a) global (b) skewness (c) kurtosis (d) link function and (e) heteroskedasticity for groups of DNA methylation sites binned by their mean DNA methylation level. The boxes are coloured by their mean –log10(p-value) from light yellow (low) to red (high)
