| heartrate_resting | Average resting heart rate, calculated using duration-weighted average. | duration_weighted_avg | heartrate_resting | bpm | 0 |
Methods
The table below provides details on the various methods used in the statistics, including a brief description of each.
| Label | Description |
|---|---|
| intersect_sum | Sum of intersecting values of specified metrics, aggregating overlapping data points to provide a total count or sum. |
| intersect_union_sum | Sum of the union of intersecting values, merging several metrics to provide a comprehensive aggregation across multiple metrics. |
| sleep_score | A score representing the quality of sleep, calculated using intersecting values. |
| duration_weighted_avg | Average of values weighted by their duration, ensuring longer durations have a greater impact on the average. |
| max | Maximum value of the specified metrics, providing insights into the peak values recorded. |
| min | Minimum value of the specified metrics, providing insights into the lowest values recorded. |
