Hi all, this should be a simple question, but I haven't been able to do it right.

I want to use Markov-Switching Bayesian Vector Autoregression Models (MSBVAR) that is used to examine the effect of a large economy?s stock exchange movement on a small economy?s stock exchange movement. The foreign stock exchange index follows its own dynamics (an AR process is use...

Hi all, I'm doing a very informal and unscientific poll: which kernel do you use on your CentOS machines? Not which version of the CentOS kernel, but which repository. Here are some examples I can think of off the top of my head: ==CentOS stock ==build own from CentOS SRPMs ==kernel-ml (from ELRepo) ==kernel-lt (from ELRepo) ==OpenVZ kernel ==build own from kernel.org ==other? One reason I'm curious is that on occasion there are features that I would like to have from a newer kernel (e.g., --want-replacement from md) that (AFAICT) ar...

Hi, I have a model called Stock with a value called "strength." I wrote a simple method in the Stock.rb model file to update the value of "strength" for each record in the stocks table. I created a controller called fix_controller.rb. I don''t have access to the live system, so the idea is that an admi...

...alculating the nonzero min for each row of a matrix? I have a bug somewhere in the is section of code. My first guess is how I am find the the nonzero min of each row of my matrix. The overall idea is to make sure I am investing all of my money, i.e. new.set is a set of indicator variables for each stock for a particular portfolio, i.e. 0=did not buy, 1=bought. y are the stocks I could still buy, assuming I have the money, data3[,5] are their cost, so for each portfolio, i.e. the rows of new.set I have the option to purchase another stock at a cost listed in the rows of variable remain. Obvisouly t...

Dear all, I have been importing data into R from yahoo using yahooSeries, however the older version I was using no longer works with the syntax I have developed. I downloaded the latest package and it downloads data from the U.S. just fine, but the ticker codes for the Australian stock exchange (asx) do not get downloaded. a simple example, this works (US stock): stock<-yahooSeries(symbols = "IBM", from = "1999-01-01" , to = Sys.Date(), source = NULL, frequency = "daily", try = TRUE) but this does not (asx stock): stock<-yahooSeries(symbols =...
