Table 3.

Root mean square error (RMSE), mean absolute percent error (MAPE), and mean bias (measured minus predicted) and lower and upper 95% prediction intervals (95%PI) for MET_y and time spent in sedentary behaviors (SB), light physical activity (LPA), moderate physical activity (MPA), vigorous physical activity (VPA) and moderate and vigorous physical activity (MVPA) during the unstructured PA.
