Use Of makeARIMA
Hi R-Experts, Currently I'm using an univariate time series in which I'm going to apply KalmanLike(),KalmanForecast (),KalmanSmooth(), KalmanRun(). For I use it before makeARIMA () but I don't understand and i don't know to include the seasonal coefficients. Can anyone help me citing a suitable example? Thanks in advance. ------------------------------------------

Comparison between GARCH and ARMA
Dear all R user, Please forgive me if my problem is too simple. Actually my problem is basically Statistical rather directly R related. Suppose I have return series ret with mean zero. And I want to fit a Garch(1,1) on this. my is r[t] = h[i]*z[t] h[t] = w + alpha*r[t-1]^2 + beta*h[t-1] I want to estimate the three parameters here; the R syntax is as follows: #

ifconfig hw ether and -arp
Hi, Just thought I'd mention that I spent a while battling with tinc today. I had quite a weird behaviour - in routing mode, tinc would come up fine on both hosts, but pinging hosta from hostb wouldn't work until hosta pinged hostb. I've used an earlier version of tinc before in a different environment with no problems, and vaguely remembered a more complicated tinc-up script, so I

Initial values of the parameters of a garch-Model
Dear all, I'm using R 2.8.1 under Windows Vista on a dual core 2,4 GhZ with 4 GB of RAM. I'm trying to reproduce a result out of "Analysis of Financial Time Series" by Ruey Tsay. In R I'm using the fGarch library. After fitting a ar(3)-garch(1,1)-model > model<-garchFit(~arma(3,0)+garch(1,1), analyse) I'm saving the results via > result<-model

FinTS_0.2-7
Hi, All: FinTS version 0.2-7 is now available on CRAN. This version adds two new functions: * ArchTest to compute the Engle (1982) Lagrange multiplier test for conditional heteroscedasticity, discussed on pp. 101-102 of Tsay, with examples on those pages worked in the R script in "~R\library\FinTS\scripts\ch03.R", where "~R" is your local R installation directory.

Announce: My arma_scan.R for ARIMA
Hellow all R fans, I wrote a R program for SCAN: Smallest CANonical Correlation Method for ARIMA(p,d,q) identification. (by Tsay and Tiao (1985)) I don't know if there is already one for this, but since I was unable to find one, so I did it. It's ready to download at the following page http://netstat.stat.tku.edu.tw/download.php I've tested the program and comared

fSeries GARCH(1,1)
Hello all, I am trying to use the "garchFit" function in the fSeries Package to fit a Garch(1,1) Model with t distribution. I am using the following codes. fit <- garchFit(~garch(1,1),data,cond.dist="dstd") fitted(fit) I was expecting the fitted(fit) would return the fitted volatility, but the result turns out to be a series of repeated same value. I tried to change the
