This study explores a development of the conventional
biexponential model by adding a stretching factor to the
lower diffusivity component. The superior Akaike
information content and leave-one-out prediction
performance of the stretched over the conventional model
at short diffusion time is consistent with the presence
of a diversity of diffusion environments experienced by
the slow component of the models.
