Also, the potency of different entropy estimators derived from the t -test reflects that the Shannon entropy has a higher P -value (>.001); therefore, it has a limited scope than other entropy estimators for ADHD diagnosis. WebMar 1, 2024 · The permutation entropy PEG for the graph signal X is computed as the normalised Shannon entropy PEG=−1ln(m!) m!∑i=1p(πi)lnp(πi). For time series, PEG reduces to PE. In particular, if X is a time series and G the directed path on n vertices, then for all m and L, the equality holds: PE(m,L)=PEG(m,L) (see [ 7, Prop. 3] ). flap-dragon meaning shakespeare
