When doing a sensitivity run, Vensim will run the model lots of times and change the parameters. What this graph shows is that of all the runs, 50% of them were within the yellow section, 75% within the green, 90% within the blue and 100% within the grey.

It depends what stats you want.

Open the Vensim help and search for "Stats". If this gives you what you want then great. If not, search the help for "Export" and you can get the data into Excel to calculate the stats manually.

You will need to upload the model and associated files if you need help with this.

Hi,

I believe the red line shows an output based on parameters before I started sensitivity analysis.
Is that correct?

How do I export all values 50%, 75% and so on output values?

I can export a sensitivity graph but not any values.
