has_proportional_error_model

pharmpy.modeling.has_proportional_error_model(model, dv=None)

Check if a model has a proportional error model

Multiple dependent variables are supported. By default the only (in case of one) or the first (in case of many) dependent variable is going to be checked.

Parameters:

• model (Model) – The model to check

• dv (Union[Expr, str, int, None]) – Name or DVID of dependent variable. None for the default (first or only)

Returns:

bool – True if the model has a proportional error model and False otherwise

Examples

>>> from pharmpy.modeling import load_example_model, has_proportional_error_model
>>> model = load_example_model("pheno")
>>> has_proportional_error_model(model)
True
