greekify_model

pharmpy.modeling.greekify_model(model, named_subscripts=False)

Convert to using greek letters for all population parameters

Parameters:

• model (Model) – Pharmpy model

• named_subscripts (bool) – Use previous parameter names as subscripts. Default is to use integer subscripts

Returns:

Model – Pharmpy model object
