We present a new framework for modelling the regional variation of tissue parameters estimated from diffusion MRI across white matter regions of interest. The method can be used to compare differences in parameter variation between groups and statistical tests allow the localisation of significant differences. We demonstrate the technique on the midsagittal corpus callosum and are able to detect significant differences in the genu of two distinct age groups
