Does anybody know how to calculate the quantile of a variable in Vensim (PLE plus Version)?

I need to know under which value 5 % of the data of a certain variable are located.

i tried to open the vdf-file and did not convert it to csv... Now everything is working fine. Thank you very much, you helped me a lot

now i purchased PLE plus and the sensitivity simulation is working great. Does anybody maybe know how to export sensitivity results to excel? I only can copy & paste the different graphs and charts, but can't copy the data. I need at least the mean of my variable at the end of the simulation or ...

thank you very much, the information about the "noise"-variable helped me a lot. Unfortunately I can't open the model (I think because I am using the PLE-Version). The problem if I get the time from Excel is, that I still have to launch the simulation many times manually. I would like to l...

Hi, I have a model with a random (normally distributed) variable. If I run the model several times, Vensim generates the same valuesfor my random variable in every run. Is there a possibility to change this? Can I run the model several times automatically with different random values? Just for infor...

Hi! For modelling my problem in Vensim I have to calculate the sum of a term ( I mean this Sigma sign. Sorry I don't know how it is called in English). e.g.: Sum of (1-x)^i for i=1 to k with a variable k. --> (1-x)^1+(1-x)^2+...+(1-x)^k Does anybody know how to write an expression like that in Vensi...

Thank you very much, the lookup table works fine. I didn't think about that solution

Hi

Thank you for the help but I don't understand how to calculate the probabilities. Which function in Vensim do I have to use? How is it possible to have a level variable that is constant over time? or maybe I understand that in a wrong way now....

Hi, does anybody know how to calculate values of the CDF (cummulative distribution function) of a standard normal distributed variable in Vensim? I need to know the probability that a standard normal distributed variable does not exceed a certain value. Can I calculate the inverse function somehow? ...
