The aim of this work was to compare the non linear least
squares (NLLS) algorithm to the maximum likelihood (ML)
algorithm for fitting diffusion decay curves to extract
parameters to the measured MR signal intensities as a
function of b-value for bi-exponential, stretched
exponential, and non-Gaussian (Kurtosis) models.
