How to obtain the series of residuals from fracdiff
Hi
I'm using fracdiff package to estimate the parameters of a
fractionally-differenced ARIMA (p,d,q) model, and it works fine, but I wanted
to have also the filtered series and the series of residuals.
I understand these are calculated in the subroutine fdfilt, in the program
fdcore.f, but I can't manage to get them out.
Any suggestion would be much appreciated
Thanks
Susana Barbosa

Hi Susana
For fractional differencing you can use, e.g., something like
fracdiff <- function (x, d, N = 100)
{
n <- 0:N
w <- gamma(-d+n)/(gamma(-d)*gam...
