class caps.diffusion_estimation.py_tensor_estimation.FourthOrderTensorEstimation(autoexport_nodes_parameters=True, **kwargs)

Fourth Order Tensor Estimation

Fit the diffusion tensor model using an ordinary least suquare procedure or a quartic decomposition.

Note that the adc or the orientation distribution function can be modeled.
