Epoch-level classification metrics for the classification of epochs as sit-to-stand transitions (yes/no) by CHAP-child evaluated using the transition pairing method with a 1-min window (N = 202 participant-seasons from 84 participants). Each metric was calculated for each participant-season and values at the top of the chart reflect the mean (SD) across participant-seasons. CHAP = Convolutional Neural Network Hip Accelerometer Posture classification method; SD = standard deviation; Sensitivity = correctly classified as sitting (i.e., true positives) / actual sitting; Positive Predictive Value = correctly classified as sitting (i.e., true positives) / classified sitting
