Hi there, I have a spreadsheet in excel which consists of first column of dates and then subsequent columns that refer to prices of different securities on those dates. (the first row contains each series name) I saved the excel file as type csv and then imported to excel using prices=read.csv(file="C:/Documents and Settings/Hugh/My Documents/PhD/Option prices.csv",header = TRUE, sep

m0<-epxression((4*theta1*theta2-theta3^2)/(2*x*theta3^2)-0.5*theta1*x) params<-all.vars(m0) this reads all the params from m0 so theta1,2 and 3 correct? params<-params[-which(params=="x")] checks which params are multiplied by x? np<-length(params) for(i in 1:6){ esp<-get(sprintf("m%d",i-1))

Hi there, What is the best way to get a time series of daily stock price observations into R (from excel).

What ever package you recemmned i need to be able to run a corrolelagram. Thanks Hugh -- View this message in context:

Hi there, I have a largish optimisation problem (10 years of daily observations). I want to optimise between 4 and 6 parameters. I'd like to utilise parallel computing if I can as I will have to run it with different starting values etc. I have a quad core PC with 16GB ram running windows 7. Having done a little reading it seems the two best options for me are: 1.) Use the academic

Hi there, I ran the following code: vols=read.csv(file="C:/Documents and Settings/Hugh/My Documents/PhD/Swaption vols.csv" , header=TRUE, sep=",") X<-ts(vols[,2]) #X dcOU<-function(x,t,x0,theta,log=FALSE){ Ex<-theta[1]/theta[2]+(x0-theta[1]/theta[2])*exp(-theta[2]*t) Vx<-theta[3]^2*(1-exp(-2*theta[2]*t))/(2*theta[2]) dnorm(x,mean=Ex,sd=sqrt(Vx),log=log) }

Hi Is there a way to know if a message has been dowloaded via pop3 and not seen via imap ?

While y is lower triangualr 0's with the remaining cells all ones. I really don't understand how this deceptively simple looking piece of
