Hi, My code is as the following, ratio<-seq(0,1,by=0.01) payoff<-NULL for (i in 1:length(ratio) ) { payoff1<-100*(ratio[i]>=0.7)+max(100*(1+(ratio[i]-1)*2),0)*(ratio[i]<0.7) payoff<-c(payoff,payoff1) } plot(ratio,payoff, xlab='ST/S0', ylab='Payoff',type='l') I have the discontinuous point at ratio=0.7. I do not want to have the line at 0.7, and would

Hi all i have an interesting project that i have been working on. i intended to set this as a first year programming problem but then changed my mind since i thought that it might be too difficult for them to program. the problem is as follows: You have been approached by a local casino in order to investigate the performance of one of their slot machines. The slot machine

Dear WizaRds! I am sorry to ask for some help, but I have come to a complete stop in my efforts. I hope, though, that some of you might find the problem quite interesting to look at. I have been trying to estimate parameters for lotteries, the so called utility of chance, i.e. the "felt" probability compared to a rational given probability. A real brief example: Given is a lottery

The cheapest RAID-friendly drives we?re buying these days are about US $37/TB in low quantities. A big data warehouser will be getting a substantial

Greetings! The original version of this tutorial was written by Curt Hibbs and published on ONLamp.com. It served as my introduction to both Ruby and Rails. Unfortunately, I experienced some frustration working through it. This was due first to the fact that I was using Instant Rails, not Rails, and second, to the fact that Rails itself has grown since Curt wrote the article. Despite my

Hey everyone, So I am looking for a way to create a decision tree for a modeling class and I am not all that familiar with R. I thought I might be able to use RPart, but I can't get it to work. I want a simple tree with a parent that says the amount and each child has a percentage of likelyhood and a payback so it would look something like this... _____10%/1000 100|_____90%/0 So I

Hello, this question is a bit out of the blue. I am a big R fan and user and in my new job I do some decision modeling (mostly health economics). For that decision trees are often used (I guess the most classic example is the investment decision A, B, and C with different probabilities, what is the expected payoff). We use a specialized software called TreeAge that some might know. The basic

My company built a little business application in FoxPro many years ago, and it's gradually grown into a giant ball of mission-critical haywire. We've starting porting small parts of it to PostgreSQL, but it will probably take years to complete the project. In the mean time, I've been considering the option of hacking Samba to present a set of virtual files that are actually

Hi all. I am an R newbie and trying to grasp how the simple optimization routines in R work. Specifically, I would like some guidance on how to set up a code to calculate the internal rate of return on an investment project (http://en.wikipedia.org/wiki/Internal_rate_of_return). My main problem (I think) is that I want a generic code where N (number of periods) can be easily changed and set

Hi-- About 10 days ago I switched from a Red Hat 9.0 machine as my Samba server to Ubuntu. Ever since, things have been slow. How do I mean, slow? 1st clue: previously, when I saved docs in OOo Writer, I would go ctrl-S and once every 4th or 5th time it would say it couldn't create a backup; now it is every time. So to save I have to go ctrl-S esc esc ctrl-S. 2nd clue: WinXP on login to

I know that this has been discussed (at least in passing) a few times on the list, but I couldn't locate a bug for it. Have any architectural plans been made for it? Are there architectural roadblocks with the current LLVM infrastructure that will complicate the process? What has demotivated the implementation of this so far (is it not that big a benefit on important targets, too
