According to recent research published in the journal Fractals - Complex Geometry Patterns and Scaling in Nature and Society, "The multifractal spectrum calculated with wavelet transform modulus maxima (WTMM) provides information on the higher moments of market returns distribution and the multiplicative cascade of volatilities."
"This paper applies a wavelet based methodology for calculation of the multifractal spectrum of financial time series. WTMM methodology provides a better measure of risk changes compared to the structure function approach," wrote R. Yalamova and colleagues, University of Lethbridge.
The researchers concluded: "It is well founded ...
