similar to: Re: arima in ts.

Does anyone know of any comprehensive literature (like a book, collection of articles, etc.) that walk thorugh example of ARIMA modeling with the ts package of R? Genarlly if you've just started to learn the R-language and are all week long with ARIMA, what is a fast-pace source that you would recommend (to a beginner) ? Thank you, Krasi

Hi, I was wondering if there is a standard for R function description in XML (or any plain text) format. Rd files are the closest thing I found, but they do not describe the argument (or return value) types. The purpose would be to write a program to automate the creation of C# wrapper around any R function, but without the argument type Rd descriptions are useless. Any clues... thank you

Hi, When the Dovecot 1.0.rc19 IMAP server encounters X-UID headers with gaps in them, it hangs indefinitely. I've attached a sample mailbox (in mbox format) which repeatably exhibits this behavior. The mbox contains only three messages with the following X-UIDs in order: 774, 785, 787. If I remove the X-UID headers from each message, Dovecot handles the mailbox without any problems. UW-IMAP

Hello, disclaimer/ Apologies if this is the wrong llvm/clang mailing list; please, direct me to the right one if needed. /disclaimer I've been experiencing issues with incomplete type info when debugging code generated by clang 3.5.0 from the recent release_35 branch.

I maintain the Devore5 package which contains the data sets from the 5th edition of Jay Devore's text "Probability and Statistics for Engineering and the Sciences". The 6th edition has now been published and it includes several new data sets in exercises and examples. In addition, some exercises and examples from the 5th edition are renumbered in the 6th edition. I face the

To whom it may concern: I am trying to better understand the functionality of 'R' when making arima predictions to avoid any "Black Box" disadvantages. I'm fitting a seasonal arima model using the following command (having already loaded 'stat' package). arimaSeason <- arima(Data,order=c(1,0,1),seasonal=list(order=c(1,0,1),period=12)) I can then generate

I am trying to find a way to obtain the fitted values for a model fit using arima() in the ts package. I came across a suggestion in the mailing list archive that these values can be simply calculated as: model<-arima(t, order = c(1,1,0)); fitted<-t-model$residuals; But, the help file for arima() in the ts package describes the residuals values returned as being "standardized

I've been trying to get comfy with arima() and associated functions in the ts() package. I'm thinking seriously about using this package, and R generally, in a 4th year intro time series course that I'm teaching this autumn. I have a couple of questions about arima: (1) The help file says that residuals component of the value returned by arima() consists of the

I'm trying to get more info about seasonal parameter of arima(ts). Can someone explain on its usage? I'm also interested in building a model for weekly sales for an item with covariates like consumer confidence index, promotion flag etc. Which package has functions to model and do predictions for this kind of time series data?

I did a regression with ARMA errors using arima0 with ari<-arima0(y,order=c(2,0,2),xreg=reg1,delta=-1) or ari<-arima0(y,order=c(2,0,2),xreg=reg1) where reg1 is the matrix of the regressors and when I see diag(ari$var.coef) I get negative terms. Do you know what this mean ? I try to change transform.pars to 0 or 1 but this crash R on Windows. Is it possible to test the significativity

Hi, I have the following code from Splus that I'd like to migrate to R. So far, the only problem is the arima.filt function. This function allows me to filter an existing time-series through a previously estimated arima model, and obtain the residuals for further use. Here's the Splus code: # x is the estimation time series, new.infl is a timeseries that contains new information # a.mle
