[Nonfractal-commits] how to define the scale range

[Hui-bin Jia]

Dear Wonsang,
      I have only limited knowledge about DWT. In the function bfn_mfin_ml we need to define the scale range. I think this option is used to define the frequency range in Hurst estimation.
Usually, the frequency range in fMRI analysis is defined to be [0.01 0.1] Hz. Could you give me some tips about how to define the scale range according to the frequency range?


In some papers, the authors argue that the signal length should be a power of 2 in order to obtain DWT-based Hurst exponent. I'm asking whether the signal length should be a power of 2 in function bfn_mfin_ml?


Thank you!


Best Regards,
Huibin Jia
