fSeries Garch and Arfima Ox interface
...the functions work with the latest version of Ox console (version 4)? Or do we need to use Ox version 3.40? Does somebody have it working - can you let me know how you did it? For your information, I am currently using R 2.5.1 and I am following the instructions from http://faculty.chicagogsb.edu/ruey.tsay/teaching/bs41202/G at RCH_info.txt Cheers Ian Dr. Ian McHale Lecturer in Applied Statistics Centre for Operational Research and Applied Statistics The University of Salford Maxwell Building Salford Greater Manchester M5 4WT Tel: 0161 295 4765 Fax: 0161 295 4947

ar() - AIC and BIC
Hi, I'm slowly working through Tsay's "Analysis of Financial Time Series" 3rd ed. ?I'm trying to replicate Table 2.1 on p.47, which gives PACF, AIC, and BIC for the monthly simple returns of the CRSP value-weighted index. The data: http://faculty.chicagobooth.edu/ruey.tsay/teaching/fts3/m-ibm3dx2608.txt > da <- read.table("http://faculty.chicagobooth.edu/ruey.tsay/teaching/fts3/m-ibm3dx2608.txt", header = TRUE) > vw <- da[, 3] I can replicate the PACF calculations. > x <- pacf(vw) > x Partial autocorrelations of series ?vw?, by l...

calculating recursive sequences
Hi, I was trying to repeat the estimation of threshold GARCH models from the book "Analysis of Financial Time Series" by Ruey S. Tsay, and I was succesfull, but I had to use "for" loop, which is quite slow. The loop is necessary, since you need to calculate recursive sequence. Is there a faster way to do this in R, without using loops? The model is such: r_t = \mu + \alpha_2 r_{t-2} + a_t a_t = \sigma_t\varepsi...

Jarque-Bera test and Ljung-Box test for multivariate time series
Hi! I know that there is function in fBasics package for univariate Jarque-Bera test and a funtion for univariate Ljung-Box test in stats package. But I am wondering if there is a function somewhere to do the tests for multivariate time series? Thanks, John [[alternative HTML version deleted]]

Maximum likelihood estimation of ARMA(1,1)-GARCH(1,1)
Hello Following some standard textbooks on ARMA(1,1)-GARCH(1,1) (e.g. Ruey Tsay's Analysis of Financial Time Series), I try to write an R program to estimate the key parameters of an ARMA(1,1)-GARCH(1,1) model for Intel's stock returns. For some random reason, I cannot decipher what is wrong with my R program. The R package fGarch already gives me the answer, but...

Re cursive regression
Hi there, I'm in desperate need to figure out how to solve this issue. I need to estimate a recursive model for a time series data of asset returns. The dependent variable is the asset return and then I have a set of k variables, a lagged value of the dependent variable (plus an intercept) as regressors. My sample period (monthly observations) starts on Jan 1972. What I need to do is the

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 at fit$se.coef I'm wondering how the first variance > result at h.t[1] is compute...
