ChangeModel#

class ChangeModel(stress, rfunc1, rfunc2, name, tchange, up=True, settings=None, metadata=None)[source]#

Model where the response function changes from one to another over time.

Parameters

  • stress (pandas.Series) – pandas Series object containing the stress.

  • rfunc1 (pastas.rfunc instance) – The instance of the response function used in the convolution with the stress.

  • rfunc2 (pastas.rfunc instance) – The instance of the response function used in the convolution with the stress.

  • name (str) – name of the stress.

  • tchange (str) – string with the approximate date of the change.

  • up (bool or None, optional) – True if response function is positive (default), False if negative. None if you don’t want to define if response is positive or negative.

  • settings (dict or str, optional) – The settings of the stress. This can be a string referring to a predefined settings dict (defined in ps.rcParams[“timeseries”]), or a dict with the settings to apply. Refer to the docs of pastas.Timeseries for further information.

  • metadata (dict, optional) – dictionary containing metadata about the stress. This is passed onto the TimeSeries object.

Notes

This model is based on Obergfell et al. [2019].
