Hi All, I'm currently doing nightly full backups of /home. I'm not sure if a full back up is the best way to do backups. I know with my fileserver i do weekly full backup and daily incremental which would file on those type of files. I guess my question to the group is, how do you guys backup Maildir? whats the best way of doing it? -- Gabe Granger Pancentric results-driven

Dear Community, this is my first programming in R and I am stuck with a problem. I have the following code which automatically calculates Granger causalities from a variable, say e.g. "bs" as below, to all other variables in the data frame: log.returns<-as.data.frame( lapply(daten, function(x) diff(log(ts(x))))) y1<-log.returns$bs y2<- log.returns[,!(names(log.returns) %in%

Hi all, I'm using Debian (testing) for my office mail. I'm using sendmail and Dovecot to deliver email to clients over IMAP using mbox format. I want to move over and start using Maildir. I know that I can use different MTA's to do the job, but I really like sendmail, and I run additional sendmail servers across the my internal and external networks. I'm probably

Dear Community, For my masters thesis I need to perform a multivariate granger causality test. I have found a code for bivariate testing on this page (http://www.econ.uiuc.edu/~econ472/granger.R.txt), which I think would not be useful for the multivariate case. Does anybody know a code for a multivariate granger causality test. Thank you in advance. Best Regards -- View this message in context:

Does anyone know of a package that includes the Modified Sims test [Gewerke, 1983, Sims, 1972]? This test is used in econometrics and is a kind of alternative to the Granger test [Granger, 1969], which is in the package lmtest. Thanks in advance, chris Refernces: Gewerke, J., R. Meese, and W. Dent (1983), "Comparing Alternative Tests of Causality in Temporal Systems: Analytic Results and

I've got some issues with dovecot, that I need to resolve, I only have about 20 users in the office, but the average disk space used by each user is anywhere from 1GB up to at the extreme end of the scale 7GB. I'm using the mailbox format. The server is a P4 2.8 with a 1GB of ram and run off 250GB SATA disks. most users have lots of structured folders going as deep as 6 levels.

Hello dudes. I'm developing VAR analysis based on suggestions made by Horváth in its paper Canonical Correlation Analysis and Wiener-Granger Causality Tests. That's the reason I'm looking for if there's any R package to develop Wiener - Granger Causality Test. Thanks a lot for your unvaluable help. Regards from Mexico [[alternative HTML version deleted]]

Dear R Users, Can someone point me to a R package which will help me optimally choose a lag for Granger Causality testing ?

Dear Community, I am new to R and have a question concerning the causality () test in the vars package. I need to test whether, say, the variable y Granger causes the variable x, given z as a control variable. I estimated the VAR model as follows: >model<-VAR(cbind(x,y,z),p=2) Then I did the following: >causality(model, cause="y"). I thing this tests the Granger causality of

Dear Achim, R Users, What am I doing wrong in this example ? a<-zoo(rnorm(100),order.by=1:100) b<-lag(a) regr<-na.exclude(merge(a,b)) plot(regr) grangertest(regr[,1],regr[,2],3) > a<-zoo(rnorm(100),order.by=1:100) > b<-lag(a) > regr<-na.exclude(merge(a,b)) > plot(regr) > grangertest(regr[,1],regr[,2],3) Error in solve(vc[ovar, ovar]) : subscript out of bounds

Dear R Users, The granger.test command in the MSBVAR package estimates all possible bivariate Granger causality tests for m variables. If one passes a data frame with 3 rows, it returns 6 granger tests in two rows, one for the F-statistic and another for the p-value. For example: > a<-rnorm(1:10) > b<-c(lag(a),rnorm(1)) > c<-c(lag(b),rnorm(1)) >

I?m a PhD student at the University of Warsaw, and have started using R. In many books they specify to use <- instead of = when assigning values, and this is also mentioned in older posts on the R website. However, it seams to me that some update has occured, becuase I continously get the same result wether I use <- or =. I would be extremely helpful for any answer to this. = seams more

I am new to samba but becuase I use squid and I want to track my authenticated users I installed samba 3 but keep hitting dead ends on how to add it to the domain etc. I can't seem to even get the smbd to startup. I got swat keying into the smb.conf but it ended up in another directory so I don't think that is configured. I can't even find good documentation to see if samba is even

i have an NT4 server and a linux samba server. the NT4 server is currently the WINS server. it works perfectly. i want to ditch it and use my samba server as the WINS server, however WINS simply does not work. could this be becuase the WINS server also needs to be the local master browser? here is the global section of my smb.conf [global] workgroup = laboratory os level = 2

Hi, Please tell me the R codes for Engle Granger Test of cointegration. TIA Aditya

Hi useRs.. I cant figure out how to test for causality using causality() in vars package I have two datasets (A, B) and i want to test if A (Granger)cause B. How do I write the script? I dont understand ?causality. How do I get x to "contain" A and B. Further using the command VAR() to specify x, I dont either understand. Kind regards Tobias -- View this message in context:

Hi All, Bit the bullet last night and switched off UW-IMAP and turned on Dovecot. With any migration I've got some teething problems and hoping someone might be able to point me in the right direction. I tested the system using apple's Mail.app which worked fine, no problems at all, but it seems that most of my users are getting problems, i suspect Mail.app is hiding these messages
