Table 3. Performance results of three single parameters as well as one compound indicator, being a SVM with an RBF kernel using 20 parameters.
PK analysis was performed using a bootstrap evaluation based on the data from the ten held back patients (test set).
| Parameter / Classifier | PK with 95% confidence intervals |
|---|---|
| WSMF (fhigh = 49 Hz) | 0.910 (0.822 to 0.977) |
| PeEn (fhigh = 49 Hz) | 0.935 (0.859 to 0.990) |
| maximum amplitude of retransformed AEPs of wavelet level D3 | 0.860 (0.764 to 0.940) |
| Compound indicator | 0.921 (0.764 to 0.940) |
fhigh = cutoff frequency of the low-pass filter, PK: prediction probability, PeEn: permutation entropy, WSMF: weighted spectral median frequency, AEP: auditory evoked potential.
