Table 3.

The subset of the top 10 selected features using RRCT are presented for estimating diagnosis (upper section) and stroke severity group (lower section) for the respective feature groups (defined by vertical labels). Adjacent to each feature the “stability score” (%) for that feature is presented. Demographics were included in all feature groups prior to feature selection to account for their potential effect on model performance. WD and WE denote weekdays and weekends, respectively. IN denotes inactivity, LIG denotes light activity, MOD denotes moderate activity, VIG denotes vigorous activity, and MVPA denotes moderate to vigorous activity; “wei” indicates a weighted average across available days, with weekend days weighted 2/5 weekdays.
