fix_parameters

pharmpy.modeling.fix_parameters(model, parameter_names, strict=True)

Fix parameters

Fix all listed parameters

Parameters:

• model (Model) – Pharmpy model

• parameter_names (list or str) – one parameter name or a list of parameter names

• strict (bool) – Whether all parameters in input need to exist in the model. Default is True

Returns:

Model – Pharmpy model object

Example

>>> from pharmpy.modeling import fix_parameters, load_example_model
>>> model = load_example_model("pheno")
>>> model.parameters['POP_CL']
Parameter("POP_CL", 0.00469307, lower=0.0, upper=∞, fix=False)
>>> model = fix_parameters(model, 'POP_CL')
>>> model.parameters['POP_CL']
Parameter("POP_CL", 0.00469307, lower=0.0, upper=∞, fix=True)
