!!! note "Assumptions/Observations"
    
    1. _Active and sedentary bouts_. If the step count per minute is smaller than `THRESHOLD_ACTIVE_BOUT` (default value is 10), that minute is labelled as sedentary, otherwise, is labelled as active. Active and sedentary bouts are periods of consecutive minutes labelled as `active` or `sedentary`.
