Dear R Helpers, Is there any literaure available (including R code) on Fast Fourier Transform being used in CreditRisk+? I need to learn how to apply the Fast Fourier Transform. I agree I am too vaue in my question and sincerely apologize for the same, but I am not able to understand as to where do I start for this particular assignment. I tried to search google for CRAN and Fast Fourier Transform, but I got something for FFT image. Basically I need to understand what is Fast Fourier Transform is and its use in CreditRisk+? With regards and tahnking in advance Maithili
schmway and morgan time series analysis with R examples is a good intro to fourier analysis. Also there are probably references in the help for ?fft Stephen On Thu, Mar 5, 2009 at 5:48 AM, Maithili Shiva <maithili_shiva at yahoo.com> wrote:> > Dear R Helpers, > > Is there any literaure available (including R code) on Fast Fourier Transform being used in CreditRisk+?

[R] Fast Fourier Transform w.r.t. CreditRisk+
Hello, You have a link on the subject here: http://papers.ssrn.com/sol3/papers.cfm?abstract_id=1122844 The author has extra literature and code on the subject. Also, there was a thread in R-SIG-Finance list on the subject a few months ago. Best regards, Carlos J.
