Hi All, This question regards the estimation of oil volumes using the volumetric equation. I understand why (using the central limit theoremm as an argument)...
Otto, In my experience, I have no information to suggest that the uncertainty distribution of any of the variables used to estimate oil and gas recoverable...
Hi, Otto, When considering a volumetric product to estimate resources or reserves, conventional wisdom has it that factors like volume, which can be conceived...
Hi, There I want to forecast the production of citrus for the next year. The time-series forecast should be on a weekly basis for the 52 weeks starting January...
I am batch fitting 132 datasets. I need to extract the parameters. I am assuming Pareto for all datasets. Is there an easy way to extract the pareto shape...
I set correlations between various assumptions and then ran the simulations. However, I got the error message of inconsistent correlations. How do I best...
Hi Yolanda, Great question. Here are a few comments. First, CB Predictor uses eight different "formal" time-series method (see the CB Predictor User Manual,...
Hi Andrew, This is not an easy question, but there is indeed a way - you can estimate (using MLE) both parameters of the Pareto directly from the data. In the ...
Hi Businessval, That is indeed a very good explanation. To expand a bit on that, here a quick note about both correlations measures: Pearson correlation: *...
Hi Andrew, Just to add to yesterday's posting about the Pareto distribution, you could also create a report of the fitted assumptions. This report would output...
How can I populate the CBpredictor values of Crystal Ball 7 Premium Edition to SQL server2000. Other than DTS import or bulk insert of .xls sheet , is there...
Hello, There is no way to populate data from/to a database directly to/from CB Predictor, other than the ways provided by MS Excel. You will have to first...
I need to create a macro in the CBAfterSimulation(...) interface that checks the value of certain cells and then, given the right conditions, changes two input...
Dear Samik, Thanks a lot for the information. Infact we have implented Bulk insert by scrapping the excel data to SQLserver by selecting the correct ODBC...
Hi, Does anybody know if the new version of CB (7.3) is compatible with Windows XP and Excel 2003? According to Decisioneering web page, the best version for...
Mikel, I downloaded CB 7.3 onto my Windows XP and Excel 2003 system and it works fine. Also, the following is borrowed from the Decisioneering website as of...
I like to carry out a tolerance model for a Maximum Material Condition where the size variation selected affects the positional tolerance allowable. Any...
Hello, I've set up the UD-Macro CBAfterSimulation according to the manual and checked the according box in Run-Preferences, but when the simualtion stops it...
Hi, I have an interesting problem that requires the forecast of one simulation to become the assumption for another simulation. Normally, I would just create...
Hi, I'd like to know if any compatibility problem between CB 7.2 and BC 7.3 has been reported. We are considering the migration from version 7.2 to version 7.3...
Please refer to the migration document on our web site: http://www.crystalball.com/support/installation/cb7migration.html ... Subject: [CBUG] New CB 7.3 From:...
Hi, The issue you are dealing with is continuous versus discrete data, which is a feature selection in a decision variable, but not the assumption or forecast...
Hi William, no the syntax was alright. I found out that it won't work in the Workbook Codepage/Module but only in a Worksheet Module. Thanks for your help! H....
Hi, We have a complex Montecarlo model for the yearly budget on Crystal Ball 7.2. We have modelled the budget of every business unit. One of the business units...
Hi, Does anyone know why the sensitivity data you get when you use the Extract Data menu option is different to the data you get via the sensitivity charts? ...
Hello, I would strongly suggest to look at OptQuest - he solver which comes with Crystal Ball Pro. You are actually trying to solve a stochastic optimization...
Hi, For the sensitivity data, there is 2 types. One is the variance and the other is the correlation. When you extract the data, the value is the correlation...
Hi, Actually, the two types of sensitivity analysis parameters show in Crystal Ball are based on the same calculations. More precisely, the numbers in the ...
