Input variables

Definition

Input variables are the parameters or factors that are fed into a model or analysis to determine the outcomes or results of that model. In sensitivity analysis, these variables are crucial as they allow for the examination of how changes in inputs can affect outputs, helping to identify which variables have the most influence on the overall outcome.

5 Must Know Facts For Your Next Test

1. Input variables can include financial metrics, market conditions, operational efficiencies, and more, depending on the specific context of the analysis.
2. Sensitivity analysis focuses on changing one input variable at a time while keeping others constant to isolate its effect on the output.
3. Identifying critical input variables is essential for effective risk management and decision-making in business valuation.
4. The relationship between input variables and output results can be nonlinear, meaning small changes in inputs can lead to significant variations in outputs.
5. Using software tools can enhance sensitivity analysis by allowing for complex models to be run quickly, providing insights into how different scenarios affect outcomes.
