FracFit: A robust parameter estimation tool for fractional calculus models

Abstract Anomalous transport cannot be adequately described with classical Fickian advectionā€dispersion equations (ADE) with constant coefficients. Rather, fractional calculus models may be used, which capture salient features of anomalous transport (e.g., skewness and power law tails). FracFit is a parameter estimation tool based on spaceā€fractional and timeā€fractional models used by ā€¦
