unconstrain_parameters

pharmpy.modeling.unconstrain_parameters(model, parameter_names)

Remove all constraints from parameters

Parameters:

• model (Model) – Pharmpy model

• parameter_names (list) – Remove all constraints for the listed parameters

Examples

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

Returns:

Model – Pharmpy model object
