Dimensional complexity of the stroke patient group compared with the normal group.

Comparing the results of bare time series to those of surrogate series, we confirm the low-dimensional chaos in nine time series in the patient group, which are labeled by daggers (†). If we ignore the X-component time series of patient #6, which suffers from the technical limitation, dynamics of each component of patients #1 and #5 turns out to be low-dimensional chaos. The two lowermost rows display the average values of the dimensional complexity, together with standard deviations. Comparing the values of the patient group with those of the normal one, we confirm that the differences are statistically significant (student’s t-test, p X- and Z-components; these are labeled by asterisks(*). The embedding dimension is again given by m = 26.Dimensional complexity of the stroke patient group compared with the normal group.
