- class featuretools.primitives.AvgTimeBetween(unit='seconds')[source]¶
Computes the average number of seconds between consecutive events.
- Description:
Given a list of datetimes, return the average time (default in seconds) elapsed between consecutive events. If there are fewer than 2 non-null values, return NaN.
- Parameters
unit (str) – Defines the unit of time. Defaults to seconds. Acceptable values: years, months, days, hours, minutes, seconds, milliseconds, nanoseconds

>>> from datetime import datetime >>> avg_time_between = AvgTimeBetween() >>> times = [datetime(2010, 1, 1, 11, 45, 0), ... datetime(2010, 1, 1, 11, 55, 15), ... datetime(2010, 1, 1, 11, 57, 30)] >>> avg_time_between(times) 375.0 >>> avg_time_between = AvgTimeBetween(unit="minutes") >>> avg_time_between(times) 6.25
