wherein N equals the number of b-factors, and
wherein Nf=N−Np, and
wherein Np equals the number of free fit parameters, and
wherein α(θi)is an estimated mean value of absolute noise residuals at a specific signal-to-noise ratio θi of a Rician signal distribution with σg=1;
wherein ŝi is the best fit equation result, and
wherein si is the measured signal.
