similar to: ARCH modelling/MA process

Hi I have a problem on how to proceed with further steps in my analysis. I did a linear OLS regression (ri,t=alpha*beta*rm,t+et) with my daily data of stock and index returns. There is now the problem of arch in my error terms. Thus I used the following r command: /garch(resid_desn, order=c(0,2)) ## This ARCH(2) process seems to fit the best after trial and error. Consequently, I get there

The specific standards process used to develop the MPEG codecs creates patent minefields that royalty-free codecs don't generally face. Because many knowledgeable people have heard of the problems faced by these patent-soup standards, they may extrapolate these risk to codecs developed under a different process where these problems are less considerable. This is a mistake, and I'll explain

Dear list members, Any help on this efficiency issue would be greatly appreciated. I would like to find the most efficient way to run a non-vectorized function (here: fisher exact test p-value) iteratively using 4 matrices with identical dimensions. And as a result I aim for an array with identical dimensions containing the corresponding p-values. Please consider some code using a trivial

I am doing a Search in my ''properties'' table on column ''name'' using in my controller : conditions = ["name LIKE ?", "%#{@params[:query]}%"] unless @params[:query].nil? this ''properties'' table has a FK (owner_id) in teh column ''owner'' to link it with the table Users... I can display the owner.name, and

Hi everyone, I am performing the time series regression analysis on a series of data sets. A few data sets followed an ARMA(1,1) process. However, they all had a same value of moving average MA coefficients = -1, constantly, from output of function “arima" . Example: > arima(residuals, order=c(1,0,1)) Call: arima(residuals, order = c(1, 0, 1)) Coefficients:          ar1      ma1  intercept

Dear colleagues, I am relatively new to R and time series and so I am experiencing difficulties in interpreting the output of "arima" in MA models (but not in AR models). I cannot make sense of the 1st innovations returned by "arima". In an AR(1) model I expect data[t]=phi1*data[t-1]+a[t] and in a MA(1) model data[t]=a[t]+theta1*a[t-1]. My interpretation from R-help is

Dear R People: I ran an ARIMA(1,0,1) on a particular series in R and got a negative MA(1) estimate. Then I ran an ARIMA(1,0,1) on the same series in Minitab and got a positive MA(1) estimate. The values are about -0.69 and 0.70. Does R show the opposite value, please? Thanks, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston -

Hello, I asked this question on the r-finance list server and didn't get a reply. Thought I would try here to. I am trying to deseasonalize some financial time series data and I wanted some feedback on the best methods for doing this. I found two Centered Moving Average and Holt-Winters. Which is better and/or more appropriate for financial time series data in your opinion? I understand

I'd like to start offering my server's users multi-factor authentication. Right now, I funnel all authentication through dovecot. Before I get too far down the fantasy design path, I'm wondering if anyone else has already done this and could share some details or code. (I loaded up the subject line with acronyms to show how serious I am. :-)) I am specifically thinking of
