hi all, i am using a dcc model for my senior thesis, it looks at stock returns during times of market uncertainty. my current rfile is below. library(SparseM) library(quantreg) library(zoo) library(nortest) library(MASS) library(fEcofin) library(mvtnorm) library(ccgarch) library(stats) library(foreign) #dataset<-read.csv(file="xxxx",header=FALSE) attach(dataset);

Hello, I have a few questions concerning the DCC-GARCH model and its programming in R. So here is what I want to do: I take quotes of two indices - S&P500 and DJ. And the aim is to estimate coefficients of the DCC-GARCH model for them. This is how I do it: library(tseries) p1 = get.hist.quote(instrument = "^gspc",start = "2005-01-07",end =

Hello, I am trying to model a bivariate time series called 'residuals' as a dcc-garch model. I want to use the function dcc.estimation(a, A, B dcc.para, dvar, model) to estimate the parameters. No matter how I tried to define a, A and B, I always got the message "Error in constrOptim(theta = para, f = loglik.dcc2, gr = grad.dcc2, ui = resta, : initial value not

Dear R-help members, I am trying to plot annotate a filled contours plot (with filled.contour) with a grid of points. I have read ways of annotating it with individual points but not with grids in another matrix. Any ideas? Thank you very much.

Hello all, I'm having trouble installing the package 'gregmisc'. I've run the command: > R CMD INSTALL -l /usr/lib/R/library /tmp/gregmisc_0.9.0.tar.gz And I can see it shows up on the list of available packeage when I issue > library() But when I do >library(gregmisc) I get: Error in parse(file, n, text, prompt) : syntax error on line 3105 All the other packages

Dear All, Sorry to bother I want to write a function in R using if Say I have a dataset x, if x[i]<0, then x[i]=x[i], if x[i]>0, then x[i]=0 for example, x=-3:3, then using the function, x becomes [-3,-2,-1,0,0,0,0] I write the codes as follows, gjr=function(x) {lena=length(x) for(i in 1:lenx) if (x[i]<0) return (x[i]) if (x[i]>0) return (0) x} but then, doing gjr(x? it only

Hello Folks, I'm a Brazilian student. I'm doing some labs about SAMBA4 AD DC with 4 domain controllers (03 Linux Debian 8 x64 with SAMBA 4.3.1 installed by souce packeage and 01 Windows Server 2008 R2 Standard x64 to study for LPIC3 certification exam.)

Dear all, I have a problem with the command 'getURL' from the RCurl package, which I have been using to obtain a ftp directory list from the MOD16 (ET, DSI) products, and then to download them. (part of the script by Tomislav Hengl, spatial-analyst). Instead of the list of files (from ftp), I am getting the complete html code. Anyone knows why this might happen? This are the steps i

Witam Anybody know how to deal with dcc irc sessions? I want to put them to lower priority queue, but i dont know how to track them, and then mark to use with fw filter. I tried iptables with -m helper --helper irc, but it seems to match only outgoing dcc sessions. But what about incoming? I''m shaping traffic from and to my small, NATed lan. -- Pozdrawiam Marcin

Hi, I am trying to fit a multivariate time series model using DCC GARCH model and forecast it. The data looks like this: > head(datax) x vibration_x Speed 1 2017-05-16 17:53:00 -0.132 421.4189 2 2017-05-16 17:54:00 -0.296 1296.8882 3 2017-05-16 17:55:00 -0.572 0.0000 4 2017-05-16 17:56:00 -0.736 1254.2695 5 2017-05-16 17:57:00 0.000

Hi, I have used R rmgarch package to implement EGARCH ADCC model from which I can extract conditional covariance matrix. Now I would like to introduce positive and/or negative shocks to see the asymmetric response of covariance. I have come to know that impulse response function (IRF) or volatility IRF is not compatible for any asymmetric models, therefore, the only way to introduce shocks into

Hello, I am trying to complete a response function analysis using the command dcc in the package 'bootRes'. Here is my code: DC<-read.table("Dalton.txt", header=T) climate<-read.table("climate.txt", header=T) dcc.DC<-dcc(DC, climate, method ="response", start = -4, end =9) My data is formatted correctly for this analysis, with 'DC' being a
