Write up an answer and post it. Perfectly fine to answer your own question around here.

Just curious, can you describe what kind of time series you want to analyze?

comment Help with calculating a complicated integral
@DuyNguyen -- Note how I formatted the functions and output you describe in the last section of your post so that it becomes clearer. It now better shows what comes from theory and what you've done in Mathematica. Even this little bit of formatting can help the participants in the forum, focus better on the parts of the problem where in they can best help.

comment Help with calculating a complicated integral
@DuyNguyen -- Focus in on the problem and revise the question when you learn a bit more. That will get you the most help from this forum. Good luck with this, you have an interesting question.

comment Help with calculating a complicated integral
@m_goldberg -- I think the question has merit. Wouldn't the OP and this site better benefit from improving the question rather then closing it. The OP has done a lot of work, trying to solve his problem. That alone merits praise. As it stands the question seems focused on the problem of translating the computation into code. I recommend the poster analyze the code and step through the calculations to identify the specific part of his code where the calculation goes wrong. This may point him to a Mma problem or a translation problem.

comment How to take derivative of a interpolated function inside the module
Not enough time now to test this, but have you tried: makeDeriv[f_InterpolatingFunction] := D[ f[x], x] ,deriv[x_] := makeDeriv[interpolated], and qq[x_] := makeDeriv[interpolated]? The ":" might help.

comment How to simulate Multifractional Brownian Motion?
Hmmm...? After reading through link, I don't know whether you want to look at Mandelbrot's implementation o this sort of thing or something else entirely. The paper does reference him. What do you want to accomplish? What problem do you want to solve or model with this?

comment Can Mathematica 10 do elliott wave calculations?
@J.M. -- And we synchronistically have a new question How to simulate Multifractional Brownian Motion? about doing just that! Mandelbrot introduces some nuance in the book over the SciAm article I mention above, but basically he applies a random process to both time and volatility. Everything else just details.

comment How to simulate Multifractional Brownian Motion?
Rather than trying to just translate, why not go back to the original sources and develop it from them. It will give you a better understanding of what Mandelbrot does and I'd wager a more elegant Mma implementation. See answer to this question for references. Mandelbrot essentially applies random selection to both time and volatility. Everything else just details.

comment Can Mathematica 10 do elliott wave calculations?
and Parrando's Paradox! Take two losing strategies, randomly switch between them on each successive move and you can arrive a a strategy the wins! Again very tough to implement, but it has an explanation for why it works. I FULLY ACCEPT ANY DISCIPLINARY MEASURES THE SITE WANTS TO APPLY FOR MY RUNNING ON. ;-(
