WMF on Unix
A few of you have helpfully sent me references to WMF formats. There is also some code to _read_ it at http://www.csn.ul.ie/~caolan/docs/libwmf.html However, the issue is to _write_ WMF on R under Unix. I am told (by someone who has tried) that the problem is the if you write a WMF file according to the published specs (which were once issued by Microsoft) you find that e.g. Word does not read it as you expected. It seems to...

Change log(J) to log(J+1) to stop log(0) from occurring in harModel
I think the code is part of the RTAQ package but is not included in it, as I obtained it from https://r-forge.r-project.org/scm/viewvc.php/pkg/RTAQ/R/HAR_model.R?view=markup&root=blotter&sortby=author&pathrev=1028. It is not my code and I make no claim to other's good work, and apologize if I should even be posting it I am not sure, but in the transform function it allows to

Generic asset definitions and management
(The following is not a Rails-specific question, but relates to a problem that affects Rails, so I wonder whether anyone on the team has an opinion about it or knows whether a solution is already in development.) While gem dependencies can be easily managed in a Gemfile by Bundler, when it comes to other assets, you either have to manually copy javascript files into the app/assets or vendor

Switching log(J) to log(J+1) to avoid log(0) in HAR-RVJ model
I am working with xts dependent data, and my code is as follows (the problem is explained throughout): dat <- getdat("prices") dat <- read.zoo(dat, sep = "",format="%d/%m/%Y %H:%M", tz="", FUN=NULL, regular=TRUE, header=TRUE, index.column=1, colClasses=c("character", "numeric")) dat <- as.xts(dat)

Writing HAR-RV-CJ Model?
I am trying to write a loop to forecast realized volatility over successive days for the purpose of VaR prediction using the HAR-RV-CJ model which is as follows: log(RV_t+1) = ?_0 + ?_CD log(CV_t) + ?_CW log(CV_t-5) + ?_CM log(CV_t-22) + ?_JD log(J_t) + ?_JW J_t-5 + ?_JM J_t-22 + e_t where RV is realized volatility, CV is continuous volatility and J is the jump which is RV - CV, _t is
