FittableModel¶

class
astropy.modeling.
FittableModel
(*args, meta=None, name=None, **kwargs)[source]¶ Bases:
astropy.modeling.Model
Base class for models that can be fitted using the builtin fitting algorithms.
Attributes Summary
Function (similar to the model’s
evaluate
) to compute the derivatives of the model with respect to its parameters, for use by fitting algorithms.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¶
