95% range of volume estimates, $E_1$, against sample size for each fitting method. The plots show the mean across age of the 95% intervals of volume errors ($E_1$), shown as a percentage of the mean, of the 1st percentile (left column) and 5th percentile (right column) curves, for linear mean and constant variance ground truth (top row) and non-linear mean and non-constant variance ground truth (bottom row). Results for the 10th percentile were very similar to those for the 5th percentile and are shown in Supplementary Fig. S2.
