Ground reaction kinetics estimation statistics. Normalized root mean square error (NRMSE) for the three analysis groups on each of the three tasks. The quality of fit is stronger for the single-trial, intra-day groups than for the single-trial, inter-day group. The multi-trial, inter-day group shows that training on a large multi-task and trial dataset can reduce the inter-day error. Component Names: Anterior-Posterior Force (F ap ), Vertical Force (F v ), Medial-Lateral Force (F ml ), Anterior-Posterior Center of Pressure (C O P ap ), Medial-Lateral Center of Pressure (C O P ml ), Vertical Torque (T v )
