Parameters:

params (ndarray) – reduced parameter array

Returns:

paramsfull – expanded parameter array where fixed parameters are included

Return type:

ndarray

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.
