statsmodels.miscmodels.tmodel.TLinearModel.expandparams¶
- TLinearModel.expandparams(params)¶
expand to full parameter array when some parameters are fixed
- Parameters:
- params
ndarray reduced parameter array
- params
- Returns:
- paramsfull
ndarray expanded parameter array where fixed parameters are included
- paramsfull
Notes
Calling this requires that self.fixed_params and self.fixed_paramsmask are defined.

This can be used in the log-likelihood to …
this could also be replaced by a more general parameter transformation.
