Identifying short- and long-time modes of the mean-square displacement: An improved nonlinear fitting approach
This paper is concerned with fitting the mean-square displacement (MSD) function, and extract reliable and accurate values for the diffusion coefficient D. In this work, we present a new optimal and robust nonlinear regression model capable of fitting the MSD function with different regimes correspo...
