Features derived for the three frequency bands.

Features	Definition
Power in low-frequency band ($P_{Low})$	$P_{Low}$ = ${{\displaystyle \sum }}_{i=1}^{i_{-tr1}}{P}_i$
Power in tremor-frequency band ($P_{Tr})$	$P_{Tr}$ = ${{\displaystyle \sum }}_{i=i_{-tr1}}^{i_{-tr2}}{P}_i$
Power in high-frequency band ($P_{High})$	$P_{High}$ = ${{\displaystyle \sum }}_{i=i_{-tr2}}^{i_{-16}}{P}_i$
Relative power in low-frequency band ($P_{rl\_Low})$	$P_{r{l}_{Low}}$ = $\frac{P_{Low}}{{{\displaystyle \sum }}_{i=1}^n{P}_i}$
Relative power in tremor-frequency band ($P_{rl\_Tr}$)	$P_{r{l}_{Tr}}$ = $\frac{P_{Tr}}{{{\displaystyle \sum }}_{i=1}^n{P}_i}$
Relative power in high-frequency band ($P_{rl\_High})$	$P_{r{l}_{High}}$ = $\frac{P_{High}}{{{\displaystyle \sum }}_{i=1}^n{P}_i}$
