May 15	comment	Compute a time series of daily volatilities in R @JenBohold I downvoted it and not closed it; as a mod, I could have been more radical. Feel free to upvote if you like the question.

May 15	comment	Compute a time series of daily volatilities in R When your previous question was closed, your were asked to look at the faq. Assuming you did, you must have understood that this site is dedicated to quantitative finance professional. Hence, with a question such as "Compute a time series of daily volaility in R", there is little chance that it will stay open. This is simply a language-specific question.
May 12	comment	Parameter estimation of Ornstein–Uhlenbeck and CIR processes I'm purging the comments and putting an end to this. QuantSE is about helping out people on things you know, and benefiting from other on things you don't know. There is no place here for negotiating reputation points. Had you given your answer, 5 upvotes would have given you the 50 points of the bounty. If you want additional points, ask good questions or solve unanswered questions. In general guys, comments boxes are no courtrooms. Please for this site's sake, stop arguing in comments, do it on the chat rooms if you really need to argue about something important.
