PySeismoSoil.helper_gof_scores.d_567(measurement: ndarray, simulation: ndarray, fmin: float | None = None, fmax: float | None = None, baseline: bool = True, show_fig: bool = False) → tuple[float, float, float][source]#

Calculate the 5th, 6th, and 7th goodness-of-fit scores in the GoF scheme described in Shi & Asimaki (2017).

Parameters:

  • measurement (np.ndarray) – Measured time history. Must be two-columned.

  • simulation (np.ndarray) – Simulated time history. Must be two-columned.

  • fmin (float | None) – Minimum frequency to be considered, in units of Hz. Default is (sampling frequency)/(length of time series).

  • fmax (float | None) – Maximum frequency to be considered, in units of Hz. Default is (sampling frequency)/2.0.

  • baseline (bool) – Whether or not to perform baseline correction of the time series.

  • show_fig (bool) – Whether or not to plot.

Returns:

  • d5 (float) – RMS Acceleration score.

  • d6 (float) – RMS velocity score.

  • d7 (float) – RMS displacement score.
