引述
"The resulting multifractal spectra are however strongly left-side asymmetric which indicates that this multifractality comes primarily from large fluctuations and small ones are more of the uncorrelated noise type."
"What is particularly interesting here is the fact that multifractality is more developed for time series representing transaction volumes than rates of return."
"On the level of these larger events a trace of multifractal cross-correlations between the two characteristics is also observed."
