Hi, I am installing CB 5.5 into my machine since that is what my class at Johns Hopkins is using (then we are suppose to upgrade to version 7), and I can not ...
Some academic versions of Crystal Ball have registration numbers with a letter in the last five digits (e.g. XXXXX-XXX-O1057). If your registration number...
I am trying to install the student version of CB (140-day trial version) in a computer where I had in the past a standard version of CB... When I try to...
Do you have enough space on your machine? Did you defrag and scandisk your machine? Do you have a file with the auth. code for the old version of the ...
well... The thing is that this was an old version of CB and I hve no clue where that auth file is in my computer... what can I do to find it and delete it?...
Sorry to bring up what must be an frequent question (though I couldn't find it in the archives), but how can OptQuest/CB be set to effectively run in the...
Hi during last presentation of Crystal Ball 7.0 I got this message: "Workbook XY was open during simulation and has since been closed or renamed, unable to...
Hi. I'm currently trying to price an option on oil using the WTI index info. But I'm at a bit of a loss about how to get that price using CB. I was thinking...
what kind of option are you trying to value? You will need to give more information before anyone can help you. Is it a European option? American? ... index ...
It's been brought to the attention of the moderators of this group that many of the postings on CBUG deal with bugs or operational problems encountered with...
Using cb 5.5 when I run a simulation and included IRR forecast sometimes I only get a chart set at the calculated IRR in the worksheet (using excel formula)...
Bob, There are a couple of things that you can check, but before I get to them, a warning about IRR. IRR is one of those things that may not be a valid thing...
IRR can give you many different returns. Even with just Excel and without CB, most projects have several different IRRs. So, use the IRR that makes NPV = 0 and...
I'm not sure if this is what you're looking for, but the equation for the negative binomial is: [(n - 1)!/((r - 1)!(n - r)!)] * p^r * (1 - p)^(n - r) where the...
The IRR function in Excel uses an iterative procedure. Think of a plot of NPV vs. discount rate. The IRR is the location where the graph crosses the horizontal...
Hi folks! I got a data set with numbers ranging from roughly 150.000 to 4,000.000 which I try to fit a distribution to. Research shows, that a Pareto...
On page 241 of Statistics for Experimenters by Box, Hunter and Hunter it states, "A linear recoding...has no effect on standard analyses. For example, t and F...
Hi, I create large Crystal Ball models which use correlation and they currently take about 10-15mins to run 50,000 simulations. I was thinking about upgrading...
Dear CBUG Member, As we hope you have heard by now, Decisioneering is holding its second annual Crystal Ball User Conference on June 13-15, 2005, at the Denver...
Dear All, I'm a new CB user, previously I used @risk for my probabilistic models. I have a problem once I converted my model from @risk to CB-based model. I...
somantri... I don't think that the problem was due to the number of forecasts. 300 is not all that many so you can put them back in. If I was a betting guy,...
Hello, This may seem trivial to most but I am only a fresher in forecasting and CB Predictor so I would appreciate your comments and help. I am experimenting...
Can anyone tell me the following : If I have a previously defined macro call M1 and I want to run it after simulation, how and where shall I write something...
The way that user-defined macros are handled has changed quite a bit in between the Crystal Ball 2000.5 (5.5) and Crystal Ball 7.x releases. You still have...
