Figure 3. Ground reaction force waveform prediction error for each subject across all conditions.

Figure 3

The average root mean square error (RMSE) across subjects was 0.16 BW (dotted line). Filled circles represent each trial, and the color indicates slope (0°, ±5°, ±10°) at three speeds (2.5, 3.33, 4.17 m/s). Open circles represent each subject’s average RMSE, horizontal bars are the median RMSE, box plot edges indicate the interquartile range (IQR; 25th and 75th percentile), and the whiskers encompass values that fall within 1.5*IQR. Subjects are sorted from lowest to highest RMSE.
