          Parameters
          ----------
          data: np.array
              Input data. Provide either phase or frequency (fractional,
              adimensional)
          rate: float
              The sampling rate for data, in Hz. Defaults to 1.0
          data_type: {'phase', 'freq'}
              Data type, i.e. phase or frequency. Defaults to "phase".
          taus: np.array
              Array of tau values, in seconds, for which to compute statistic.
              Optionally set taus=["all"|"octave"|"decade"] for automatic
