- duration_curve_slope(series, l=0.1, u=0.9, normalize=True)[source]#
Slope of the duration curve between percentile l and u after Oudin et al. .
series (pandas.Series) – Pandas Series with DatetimeIndex and head values.
l (float) – lower percentile, a float between 0 and 1, lower than u.
u (float, optional) – upper percentile, a float between 0 and 1, higher than l.
normalize (bool, optional) – normalize the time series to values between zero and one.
- Return type:
