JointFitter
(models, jointparameters, initvals)[source] [edit on github]¶ Bases:
object
Fit models which share a parameter.
For example, fit two gaussians to two data sets but keep the FWHM the same.
Parameters: - models : list
a list of model instances
- jointparameters : list
a list of joint parameters
- initvals : list
a list of initial values
Methods Summary
__call__
(*args)Fit data to these models keeping some of the parameters common to the two models. objective_function
(fps, *args)Function to minimize. Methods Documentation

objective_function
(fps, *args)[source] [edit on github]¶ Function to minimize.
Parameters: - fps : list
the fitted parameters - result of an one iteration of the fitting algorithm
- args : dict
tuple of measured and input coordinates args is always passed as a tuple from optimize.leastsq
