I was wondering how to do the sensitivity analysis on ArcGis? I see there's a guide for the version 9.2 ( ArcGIS Desktop Help 9.2 - Performing sensitivity analysis ) but I don't understand much the steps because the explanation gives for granted that I made a ModelBuilder which is not my case. I made a suitability model for urban abandoned spaces that can be reused for projects of environmental remediation and now I want to check its reliability. As I understood, the best way to do this is the sensitivity analysis but I didn't find any document or web page (apart from the one above) that show how to perform that with ArcGis specifically. So my questions is: can someone kindly explain to a beginner how to perform the sensitivity analysis, please?
Otherwise, if any of you know any other approach to check the validity of a suitability model I'd really appreciate any suggestion or tip you may have
