Hello, As a quick introduction, I'm working on a oil production forecasting model, which considers problems like scheduling, probability of success of new...
Andy's formula is (almost) the same as Huybert's formula. We use a small proprietary variation of this formula to calculate the number of bins for CS ...
Hi Andres, Great questions! Question 1: In almost all of the CB models we build for our clients we link the output of some distributions to the input for other...
Hi, I am trying to extract the values that a user sets for a crystal ball assumption to my program that controls a stochastic mixed integer program. I am using...
Dear Group, I am trying to set a simple sequence of 7 assumptions using triangular distribution, being the first correlated to the next and so on. My...
Steve, Not sure what could be causing such a dramatic slowdown. Generally, Excel 2007 is quite a bit slower in recalculating spreadsheets than Excel 2003. In...
Eric . . . Attached is the one assumption/one forecast file. I doubt that you will see the same problems as I am experiencing, but it is worth a shot. Others...
Dear Group, One solution for the problem I posted was to uninstall the Microsoft .NET Framework 2.0 pack 1 and install the Microsoft .NET Framework 2.0. I did...

Hello, I would appreciate it if someone can assist me. I have Windows Vista, Excel 2007 in my laptop and recently installed Crystal Ball 7 and Real Options...
Hi I know very little about 2d-simulation but I think I've got a problem where I'll need to go this route. I need to multiply two triangular distributions...
Hi Otto, Great questions! First, to calculate the probability that the P50 of the multiplication of the two Triangular distribution is above a certain value,...
Hello, I was wondering if anyone here is using simple lead and/or weighted lead forecasting of CB Predictor for their projects, and can provide me with some...
I have a question about how to use "Define assumptions" for a value where I know the percentiles but not the distribution. For example, if I have a value named...

Hi Greg, Great question - what you are asking for is how to construct a non-parametric distribution using this cumulative data. Since this involves a number of...
Hi Huybert, Thanks - that was exactly the info I needed. It worked perfectly. I wish they would put that in the manual for Crystal Ball! Cheers, Greg Greg...
Hi, I am new to Crystall ball. I want to get the values of assumptions and put them into some cells on the existing sheets, how can I do that? Also another...
Dear Hailey, One of the easiest ways to get the values (i.e. random samples from the assumptions) into your existing sheet is to simulate for example 1000 ...
Hi, Dear Huybert Thank you so much for your reply. I am sorry that I forgot a key thing in my question: All my questions are regarding to VBA coding. So my...
