pastas.stats.signatures.cv_fall_rate#

pastas.stats.signatures.cv_fall_rate(series: pandas.Series, normalize: bool = False, rolling_window: str | None = '7D') → float#

Coefficient of Variation in fall rate.

Parameters:

  • series (pandas.Series) – Pandas Series with DatetimeIndex and head values.

  • normalize (bool, optional) – normalize the time series to values between zero and one.

  • rolling_window (str, optional) – Rolling window to use for smoothing the time series. Default is 7 days. Set to None to disable. See the pandas documentation for more information.

Returns:

Coefficient of Variation in fall rate.

Return type:

float

Notes

Coefficient of Variation in fall rate [Richter et al., 1996]. The higher the coefficient of variation, the more variable the fall rate is, and vice versa.
