dear members, I am using arfima() from forecast package to model a time series. The following is the code: > LYGH[[202]] [1] 45.40 3.25 6.50 2.15 > arfima(LYGH[[202]]) Error in .fdcov(x, fdf$d, h, nar = nar, nma = nma, hess = hess, fdf.work = fdf$w) : NA/NaN/Inf in foreign function call (arg 5) I tried viewing .fdcov() with the following code: View(environment(fracdiff)$.fdcov) but I see no stop() with the above mentioned error message. Can you please help? THanking you, Yours sincerely, AKSHAY M KULK...

Hi,I want codes that could help me do NMA from the data. I would appreciate if you could give a dummy table with which I could practice the codes that would help read the data and calculateOdds ratio (OR) Mean difference (MD) forest plot Density plot of posterior samples Estimates of ranks probabilities Rank probabilities plot (rankogram)?...

The documentation suggests that one tries the following simple example: library(fracdiff) ts.test <- fracdiff.sim( 5000, ar = .2, ma = -.4, d = .3) fracdiff( ts.test$series, nar = length(ts.test$ar), nma = length(ts.test$ma)) When I run this, I get the following error: R --vanilla < demo.R > demo.out Warning message: unable to compute correlation matrix in: switch(temp$info, warning("warning in gamma function"), warning("singular Hessian"), This doesn't look nic...

...ive me if this is totally obvious which I'm sure it may be. Is it just a matter of expanding out the (1-L)^d term?) 2. I don't have access to the cited Haslett & Raftery (1989) paper, but could someone explain to me the little cautionary note in the help page stating that "nar and nma should not be too large (say < 10) to avoid degeneracy in the model." I see that a different implementation of the FARIMA procedure in Splus could lead to an explosive, ie. non-stationary model when it's used to fit a log volatility data set (Zivot & Wang, p.291). Zivot explains tha...

hi; When I first started looking at R code, I thought that the <- notation for assignment made the code less readable (and I still do). Then I found that now one can use "=" in place of "<-" for assignment (I understand this started since version 1.4). Anyway, I think using "=" makes the code much more readable. I was wondering, would it be safe if I

Hello! I used the function fracdiff(dn, nar=1, nma=1) and got the values of d, ar and ma coefficients. Also another coefficients were get under fdGPH, fdSperio. How could I get the forecasts in these models? Thank you very much [[alternative HTML version deleted]]

This creates libnbdkit.so as discussed in the following thread: https://www.redhat.com/archives/libguestfs/2020-March/thread.html#00203 test-delay-shutdown.sh fails for unclear reasons. This series starts by reverting "tests: Don't strand hung nbdkit processes" which is because several other tests fail randomly unless I revert this patch. I didn't investigate this yet so it
