Class SubscriberStayLengths

SubscriberStayLengths(*, locations: List[flowmachine.features.utilities.subscriber_locations.BaseLocation], statistic: str = 'max')
Source: flowmachine/features/subscriber/subscriber_stay_lengths.py

Calculate stats on the lengths of a subscriber's stays at the same location. From the provided sequence of reference locations, stay lengths are calculated as the number of consecutive locations that are the same (e.g. a subscriber with locations [A, A, B, C, C, C, A, D, D] would have stay lengths [2, 1, 3, 1, 2]), and the specified statistic is calculated over all of a subscriber's stay lengths.

Attributes
