Horizontal axis: serial standard deviation ${\sigma }_i^{\prime }$ for N = 96 mutation categories (i = 1, …, N) of cross-sectionally demeaned log-counts $X_{\mathrm{is}}^{\prime }$ across n = 14 cancer types (for samples aggregated by cancer types, so s = 1, …, d, d = n). Vertical axis: density using R function density(). See Section 2.4.1 for details.
