- Pearson correlation coefficients (CCs), p-values and signal-to-noise ratios (SNRs) between measured and decoded hand velocities in x-dimension and y-dimension are listed. Top group: the mean ± stand error of the mean (SEM) of CCs is given for each subject and dimension across all 5 folds. The average of CCs across subjects is also given. Middle group: the mean of p-values is provided for each subject and dimension across all 5 folds. Button group: the SNRs are recorded for each subject and dimension across all 5 folds. The average of SNRs across subjects is also given. Before computing CC, p-value and SNR, the measured and decoded hand velocities were smoothed with a zero-phase, fourth-order, lowpass Butterworth filter with a cut-off frequency of 1 Hz.
