classmethod from_dict(data, **kwargs)[source]#: Get prior parameters from dictionary.

classmethod from_parameters(parameters, **kwargs)#

Create model from parameter list.

Parameters:

Returns:

reassign(datasets_names, new_datasets_names)#

Reassign a model from one dataset to another.

Parameters:

datasets_namesstr or list: Name of the datasets where the model is currently defined.
new_datasets_namesstr or list: Name of the datasets where the model should be defined instead. If multiple names are given the two list must have the save length, as the reassignment is element-wise.

Returns:

to_dict(full_output=False)[source]#: Create dictionary for YAML serialisation.
