Sensitivities

Version 1.0.5

Sensitivity tests analyze how one model value, the Target, changes with variations of one or two other values, the Inputs. Instead of needing to manually create separate model infrastructure in Excel or Sheets, Parfera automates this process. The results are presented in a table that allows the user to easily understand how sensitive the target value is to changes in the input(s). Sensitivity test results are displayed on the Sensitivities tab at the bottom of the screen.
