Assumptions/Observations
- 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 asactiveorsedentary.
