The Scenario Analysis menu options allow users to change variables, parameters and relationships in the model in order to create different scenarios and analyze them. This section of the Help Menu will guild you through the process of changing these relationships and displaying those changes.

Quick Scenario Analysis with Tree

This sub-option can be reached from the Scenario Analysis option on the Main Menu of IFs. The Quick Scenario Analysis with Tree allows users to change parameters and variables with high levels of flexibility.

After you have finished with the Quick Scenario Analysis with Tree topic, you should be able to do/answer the following:

• How do I find the parameter I want to change?
• How can I upload different scenarios?
• How do I save and open files?

Change Selected Functions
