```Here is the thesis I was talking about (see attached pdf file)

I am working on an illustration (example) of the problem I'm trying to solve. I will post it to this group this weekend...

Regards,

correlation by definition is a linear measure of assocation. So what is the presice definition of non-linear correlation?
can you give the thesis......I am curious to know....

Subject: [R-SIG-Finance] determine non-linear correlation

I would like to know if two financial time-series are nonlinear correlated, and if so, what that correlation function is.
Is there an easy way to do this with R?

I have read a thesis about the "high order correlation coefficient to solve the nonlinear correlation problem" but I'm not able to translate this into a solution for my problem. All these statistics are very interesting but also challenging for me...

Kind regards,

-Mark-
