The default behavior for adding and solving with noisemodels has changed from Pastas 1.5. Find more information here

pastas.model.Model.noise#

Model.noise(p=None, tmin=None, tmax=None, freq=None, warmup=None)[source]#

Method to simulate the noise when a noisemodel is present.

Parameters
  • p (array_like, optional) – array_like object with the values as floats representing the model parameters. See Model.get_parameters() for more info if parameters is None.

  • tmin (str, optional) – String with a start date for the simulation period (E.g. ‘1980’). If none is provided, the tmin from the oseries is used.

  • tmax (str, optional) – String with an end date for the simulation period (E.g. ‘2010’). If none is provided, the tmax from the oseries is used.

  • freq (str, optional) – String with the frequency the stressmodels are simulated. Must be one of the following: (D, h, m, s, ms, us, ns) or a multiple of that e.g. “7D”.

  • warmup (float or int, optional) – Warmup period (in Days).

Returns

noise – Pandas series of the noise. None if no noise model is present.

Return type

pandas.Series or None

Notes

The noise are the time series that result when applying a noise model.

Note

The noise is sometimes also referred to as the innovations in the literature.

Warning

This method returns None if no noise model is present in the model.
