=================================

.. py:class:: pastas.noisemodels.ArmaNoiseModel



   
   ARMA(1,1) Noise model to simulate the noise as defined in
   :cite:t:`collenteur_estimation_2021`.

   .. rubric:: Notes

   Calculates the noise according to:

   .. math::

       \upsilon_t = r_t - r_{t-1} e^{-\Delta t/\alpha} - \upsilon_{t-1}
       e^{-\Delta t/\beta}

   The units of the alpha and beta parameters are always in days.

   .. warning::

      This model has only been tested on regular time steps and should not be used for
      irregular time steps yet.
