static pastas.noisemodels.ArmaNoiseModel.calculate_noise(res: pastas.typing.ArrayLike, odelt: pastas.typing.ArrayLike, alpha: float, beta: float) → pastas.typing.ArrayLike#

Calculate the noise values for the ARMA(1,1) noise model.

Parameters:

  • res (array_like) – Array of residual values.

  • odelt (array_like) – Array of time steps between observations in days.

  • alpha (float) – Alpha parameter for the noise model.

  • beta (float) – Beta parameter for the noise model.

Returns:

Array of noise values.

Return type:

array_like
