LinearLSQFitter

class astropy.modeling.fitting.LinearLSQFitter

Bases: astropy.modeling.fitting.Fitter

A class performing a linear least square fitting.

Uses numpy.linalg.lstsq to do the fitting. Given a model and data, fits the model to the data and changes the model’s parameters. Keeps a dictionary of auxiliary fitting information.

Parameters:

model : an instance of ParametricModel

Raises:

ModelLinearityError :

A nonlinear model is passed to a linear fitter
