Dear R help. Hello. I want to fit the model of "FIGARCH" on TimeSeries data. So I need to use the code of "garchOxFit". I don't know how to estimate FIGARCH model. Please let me know which package I need and what is procedure of estimating FIGARCH by R. I think I need this code! > garchOxFit(formula.mean = arma(0, 0), formula.var = garch(1,1), series =

Hi All, Currently I'm working in FIGARCH process [Fractionally Integrated Generalized Autoregressive Conditional Heteroscedasticity]. I've already got the codes to do the process in S-Plus. Can anyone help me to do it in R? Thanks, SUMANTA BASAK. ------------------------------------------------------------------------------------------------------------------- This e-mail may

Hi! I'm a new R user and I have a question about estimating VAR on a panel data. What I'm trying to do is to explain stock's volume on it's lagged volume, it's lagged returns and lagged market return's (and vice versa). In addition I have generated an exogenous variable controlling for stock's volatility. Some of you may be familiar with this experiment since it follows

Dear List, I'm now using Ubuntu 10.10 and I want to use the garchoxfit function.It seems that I need to download the package. While after installing the package,I still can't use the garchoxfit function.What's the reason and how to fix that? Thanks for your time! Best, Ning

Dear "R-listers" I've been trying to figure out how to annotate charts in ggplot (ie add text to line charts, highlighted boxes etc). By and large, I can get close to what i want with base graphics, but would ideally like to use ggplot whenever possible (additionally, i would like to add text labels automatically to the chart). The code is below I suspect I need to use geom_rect,

Hi, I am trying in R to indicate in which quintile a value of a variable is for every month of my data frame in this case based on volatility. For each month I want to know for each stock if it is in the most volatile quintile of if it is in one of the others. So far I have come up with the following function (see below). Unfortunately, the function only works in some cases and often gives the

Hello, i want to estimate a complex GARCH-model (see below). http://r.789695.n4.nabble.com/file/n4112396/GJR_Garch.png W stands for the Day of the Week Dummies. r stands for returns of stock market indices. I stands for the GJR-term. I need some help with three problems: 1.) implementation of the GJR-term in the variance equation 2.) compute robust covariance matrix

Dear All, i want to use garch model in return of stock. and the data should presence volatility cluster (Heteroscedasticity). Do you know how to test volatility cluster (the presence of heteroscedasticity) in series data of stock return in R? Is it using Langrange Multiplier (LM) ARCH test? what package i should use? I really need the help. Thanks for the attention. Eko A P

Dear all, i have daily stock prices for more than 10 years and want to compute annual volatilities for certain dates during this period. Since i have found no "easy" way to work with time data, the data presents itself in the structure TIme Index - Stock Price 1 - 15,6 2 - 17 ... ... 2010 - 28 2011- 28,5 ... 4500 - 23 Since I want to have the volatility only for certain dates, I

Dear R-helpers, I have just loaded the fSeries package and I wanted to run the example provided in the documentation of garchOxFit but I got the following: > library(fSeries) > ?garchOxFit > library(datasets) > ?garchOxFit > ## Not run: > ## garchOxFit - > # Load Benchmark Data Set: > data(dem2gbp) > x = dem2gbp[, 1] >

I fitted a gaussian mixture to my financial data. The data can be found here: http://uploadeasy.net/upload/32xzq.rar I look at the density with plot(density(dat),col="red",lwd=2) this has a skew of library(e1071) skewness(dat) -0.1284311 Now, I fit a gaussian mixture according to: f(l)=πϕ(l;μ1,σ21)+(1−π)ϕ(l;μ2,σ22) with:

Dear Sirs, I have a problem with the garchOxFit output. I want to display only the value of max.like.est and the information criteria. How can I do that; I enclose a part of GarchOxFit output, which is what I want to display.

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 my customized function

Hi,   My question is how I load the package garchOxFit. I load the fGarch function that works quite well, but I can't use the garchOxFit function. I have tried looking at Help("garchOxFit"), I as far as I can understand I am supposed to download the OxConsole Software together with the "OxGarch" Package for free somewhere. But I dont know where to download it from? I have

Hi all, I am currently optimising a small portfolio I have created as a part of my research project in Excel. I am unable to find the appropriate package to port this into R. My problem set up is as follows Minimise ABS(Sum(Xi-Xi')+10*Sum(XiMi)/Mavg) Subject to: 0 <= Xi <= 0.05 ABS(Sum(Xi)) = 0.2 where Mi - Market Cap of Stock i Xi - Initial weight of Stock i Xi' - New weight of

Hi all I am looking for an add-in. I am currently working on something and I use daily data of closing stock prices. As not all companies are traded daily (e.g. on monday, then on thursday etc) at the stock exchange, there is satistically a problem. There are some papers which explain the approach to handle infrequent trading of a stock or non synchronous data and beta estimation (Dimson, 1979;

Dear R experts---I am struggling with memory and speed issues. Advice would be appreciated. I have a long data set (of financial stock returns, with stock name and trading day). All three variables, stock return, id and day, are irregular. About 1.3GB in object.size (200MB on disk). now, I need to merge the main data set with some aggregate data (e.g., the S&P500 market rate of return,
