search for: payoff

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 ha...

...ll solve the above problem. the code is attached below. the code is very fast but i would like to improve the speed by not utilizing loops. is that possible? * another question? in the function called GAMBLING, i use the following : a<-COUNTER(reelpic,nreels,countcombs,payoffcombs,payoff,bet) countcombs<-a$countcombs payoff<-a$payoff payoffvec[i]<-payoff in order to count up the number of times each of the times we get each of the payoff symbol combinations (ie H, HH, HHH, D, DD, DDD, ... J,JJ,JJJ, Ca, CaCa, CaCaCa)....

...igured it to use domain authentication (security = domain). We slapped guest authentication on most shares, with an explicit "valid users = ...." on a small number of sensitive shares. Due to the number of users we were looking at, we set up two UNIX groups "payroll" and "payoff" and then set "valid users = +payoff +payroll" or some combination of the two. The problem I am having is that when a user that is a member of these UNIX groups connects they are rejected. I also tried using @payoff or @payroll, with the same results. Authentication works if the u...

....) it's the methodology of a simpleton, i am the first to admit, but it works, and it works well, and it works sufficiently fast. best of all, for me, is that it's extremely easy to understand. even better, for everyone: it's easy for users to understand. after all, there's no payoff in confusing the users. is there? -bowerbird p.s.

...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 payoff matrix of the type x1 x2 ... x10 median 1000 5000 ... 5000 3750 0 1000 ... 5000 2250 etc. The actual data frame consists of 11 columns and 28 rows. Each entry x1 ... x10 gives the amount of money resp. the utility of that amount you receive playing the lottery. The proba...

A big data warehouser will be getting a substantial price break on their drives, but even halving the payoff time, you?re still asking the cloud storage provider to accept a payoff time in the 18 year range.

...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 frustration, the payoff was huge. Ruby on [Instant]Rails ROCKS!!! In an effort to help "fuel the fire" I decided, with his blessing, to update Curt''s article to make it 100% keystroke-for-keystroke, window-for-window accurate for someone using this same tutorial for InstantRails Release 1.0 installed on...

...s 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 setup of such simulations is actually very simple and I guess useful in many fields. So I was wondering whether there is already a package out there in R that is doing such a thing? Thanks for any hints! Best, Stefan P...

...e client. 4) If the client write()s, do: a) Convert the string of bytes into an array of values (this process is also well defined). b) update pgtable set column1=array[0], etc... 5) If the client asks for a list of files, return the list of eligible PostgreSQL tables. ...and so on. The payoff would be that legacy code could still access the data without realizing that it was running against an RDBMS, but we could gradually transition to a pure client/server system at our leisure.

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

...le. 2. Perhaps older versions of samba are just faster than the newer ones, and I should learn to live with it. 3. Perhaps there are some tweaks in samba that I need to learn about. 4. Copy over the old smb.conf file to the new system. Where should I start? What is most likely to have a good payoff for time invested? Thanks! :- Doug.

.... 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 much time/effort for the payoff)? In toying with some code generators I've been frustrated in getting the code gen prepare pass + isel to implement the heuristics I need to match some addressing modes and I believe that whole-function isel might be the answer. -- Christopher Lamb -------------- next part -----------...
