I'm using the fixed argument in arima. Shouldn't ar4, ar5, and ar6 display as zero in the output? Call: arima(x = window(log(hhprice), start = c(1990, 1), end = c(2003, 3)), order = c(7, 1, 0), xreg = window(ts.union(exa1 = lag(exa, -1), exa12 = lag(exa, -12), exb1 = lag(exb, -1), exc1 = lag(exc, -1), exc12 = lag(exc, -12)), start = c(1990, 1), end = c(2003, 3)),

Hi dear sirs, I am wondering why the fit of the time serie x with an arima and the fit of diff(x) with an arma (same coeff p & d) differ one from another here are the output of R: %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% > modelarma<-arma(diff(x),c(7,5)) > modelarma Call: arma(x = diff(x), order = c(7, 5)) Coefficient(s): ar1 ar2 ar3 ar4 ar5 ar6 ar7 ma1 ma2 0.06078

While adding support for branch instructions in my backend, I run into a trouble. The code to handle branches looks like: void visitBranchInst(BranchInst& BI) { BB->addSuccessor (MBBMap[BI.getSuccessor(0)]); if (BI.isConditional()) BB->addSuccessor (MBBMap[BI.getSuccessor(1)]); ........... BuildMI(BB,

Hi, looking at the fresh CVS state I see: class Register<string n> : RegisterBase<n> { list<RegisterBase> Aliases = []; } while previously the Register class did not require any parameters. The change log is just: * Target.td: Revamp the Register class, and allow the use of the RegisterGroup class to specify aliases directly in register definitions. and I

Hello, I'm running a number of arima models using the "arima" function. Often, when lag length gets too high, these model don't converge and an error message appears as this: > reg <- arima(y,order=c(7,0,7),xreg=isr) Warning message: In arima(y, order = c(7, 0, 7), xreg = isr) : possible convergence problem: optim gave code=1 In this case, when you print the results

Dear list and Martin, I'm testing different approaches to fit an electricity demand time series and come upon the fracdiff package (v 1.3-1) for fitting fractional ARIMA models. The following questions are motivated by this package. 1. Despite having a help page, the residuals and fitted functions don't seem to have implementation, or did i miss something obvious? Alternatively, having a

Hello! Is there an (semi)automatic way to save registers used by a function? For example, on my target I have to store ar0-ar4 and gr0-gr4, gr5, gr6. For now I just emit huge prologue code to push them all to stack -- even if they are not modified at all. Is there a way to tell LLVM which registers must be stored, and have it automatically issue pushes/pops? I can live with current design,

Hello Everyone, I am using an HP9000 with HPUX 9.04D with gcc 2.8.1. When running configure for samba 2.03 I receive the following error: checking statvfs function (SVR4)... no checking for 3-argument statfs function (DEC OSF/1)... no checking for two-argument statfs with statfs.bsize member (AIX, 4.3BSD)... yes checking if large file support can be enabled no checking configure summary

Dear R-users, I would like to maximize the function g above which depends on 4 parameters (2 vectors, 1 real number, and 1 matrix) using optim() and BFGS method. Here is my code: # fonction to maximize g=function(x) { x1 = x[1:ncol(X)] x2 = x[(ncol(X)+1)] x3 = matrix(x[(ncol(X)+2):(ncol(X)+1+ncol(X)*ncol(Y))],nrow=ncol(X),ncol=ncol(Y)) x4 = x[(ncol(X)+1+ncol(X)*ncol(Y)+1):length(x)]
