Statistical functionals | Description |
---|---|
Relative mean of peaks | Proportion of the mean of the peak amplitudes to the mean of windowed feature. |
Kurtosis | Fourth order moment. |
Skewness | Third order moment. |
Up-level time | Number of frames that the feature is above a threshold. The threshold percentiles are set to 25, 50, 75, and 90. |
Minimum segment length | Minimum length of a particular segment. |
Mean segment length | Arithmetic mean of a particular segment. |
Inter quartile range 1-2-3 (IQR) | The range between two percentiles. The possible combination of quartiles are 1–3, 1–2, and 2–3. |
Mean distance between peaks | The mean of distances between the peaks. |
Rise-time | The time where the feature contour is rising. |
Percentile 1.0 | The minimum value of a feature. |
