Sensitivity analysis

[rbandari]

Hi all,
I have done sensitivity simulation of Mont Carlo by Vensim and now I need to assess the most influential input variables (43 input parameters) of my model. Would you please help me how can I identify the most influential input variables after doing the sensitivity simulation?

There's a tool for this coming in the next major release.

For now, a good option is to export the sensitivity output and do some analysis on the dataset using other tools. Rstudio, Python and Weka are good choices.

You can do a lot with spreadsheets Excel or OpenOffice/LibreOffice. See for example the Taylor & Ford paper on statistical screening:

Hi Tomfid, thanks for your answer, is there any paper that I can access their codes in Python or R to analyse the Vensim SA output?
