Nonlinear Least Squares Regression for Python
A walkthrough of some options for Nonlinear Least Squares Regression fitting in Python, include Scipy's curve_fit and least_squares, along with the module LMFit
This post investigates some common model selection methods, and does a detailed analysis of Akaike's Information Criterion (AIC) and how it performs on some diffusion MRI models.
Part 3: Bootstrap, Graphical Analysis, and Kurtosis Model
This post looks at the statistical bootstrap as a method to diagnose ill-conditioning, graphical analysis of regression fitting, and examines the kurtosis Diffusion MRI model.
Part 2: The Biexponential Model and Ill-Conditioning
An investigation on the biexponential model used with diffusion MRI and how it can exhibit large uncertainty in its parameter estimates
