TY: JOUR T1 - What is the best fractional derivative to fit data? A1 - Almeida, Ricardo N2 - The aim of this work is to show, based on concrete data observation, that the choice of the fractional derivative when modelling a problem is relevant for the accuracy of a method. Using the least squares fitting technique, we determine the order of the fractional differential equation that better describes the experimental data, for different types of fractional derivatives.
