aggregate_dat

Obtain table from raw accelerometer table in 1-min intervals

Provides sleep duration estimates using a Pruned Dynamic
Programming (PDP) algorithm that efficiently identifies
change-points. PDP applied to physical activity data can identify
transitions from wakefulness to sleep and vice versa. Baek, Jonggyu, Banker,
