Notice of Retraction Variability Analysis on the Parameters of Pulse Wave

The variability of pulse wave was found and discussed recently. The cross-correlation of variability of the parameters of pulse wave was studied in this paper. We found that the variability of the features in time was closely related. However, the variability of the features in time had little correlation with that of the amplitude features of pulse wave. The complexity of the variability of these features of pulse wave had little difference.
