Physical Activity Feature

We utilize physical activity features from RAPIDS-Fitbit-Steps. They include both high-level features (number of steps, duration of being active), and low-level features about the statistics of active or sedentary episodes (mean, std, max, min).

`maxsumsteps`	steps	The maximum daily step count during a time segment.
`minsumsteps`	steps	The minimum daily step count during a time segment.
`avgsumsteps`	steps	The average daily step count during a time segment.
`mediansumsteps`	steps	The median of daily step count during a time segment.
`stdsumsteps`	steps	The standard deviation of daily step count during a time segment.
`sumsteps`	steps	The total step count during a time segment.
`maxsteps`	steps	The maximum step count during a time segment.
`minsteps`	steps	The minimum step count during a time segment.
`avgsteps`	steps	The average step count during a time segment.
`stdsteps`	steps	The standard deviation of step count during a time segment.
`countepisodesedentarybout`	bouts	Number of sedentary bouts during a time segment.
`sumdurationsedentarybout`	minutes	Total duration of all sedentary bouts during a time segment.
`maxdurationsedentarybout`	minutes	The maximum duration of any sedentary bout during a time segment.
`mindurationsedentarybout`	minutes	The minimum duration of any sedentary bout during a time segment.
`avgdurationsedentarybout`	minutes	The average duration of sedentary bouts during a time segment.
`stddurationsedentarybout`	minutes	The standard deviation of the duration of sedentary bouts during a time segment.
`countepisodeactivebout`	bouts	Number of active bouts during a time segment.
