  1. The correlation with classification accuracy for purity and repeatability index. Correlations under “individual results” were calculated using classification accuracies and CCES from every individual movement, subject and feature, while those under “average result” were derived using one average CCE and classification accuracy for every subject and feature. Both methods provide one correlation, although “individual results” use more data. Classifiers were configured using AMI. All correlations were found to be statistically significant (p < 0.05)
