pastas.stats.signatures.date_min#

date_min(series)[source]#

Compute the average date of the minimum head value with circular statistics.

Parameters

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

Returns

Average date of the minimum head value.

Return type

float

Notes

Average date of the minimum head value. The higher the date, the later the minimum head value occurs in the year, and vice versa.

The average date is computed by taking the average of the day of the year of the minimum head value for each year, using circular statistics. We refer to Fisher [1995] (page 31) for more information on circular statistics.
