Attributes Documentation

col_fit_deriv = True

fit_deriv = None

Function (similar to the model’s evaluate) to compute the derivatives of the model with respect to its parameters, for use by fitting algorithms. In other words, this computes the Jacobian matrix with respect to the model’s parameters.

fittable = True

linear = False
