Sensitivity Analysis Calculator
Sensitivity analysis is a crucial process in understanding how changes in input variables affect the output of a model. It’s vital in decision-making processes, risk assessment, and model validation.
How to Use This Calculator
- Enter the values for X, Y, and Z in the respective input fields.
- Click the “Calculate” button.
- View the results below the calculator.
Formula & Methodology
The sensitivity index (SI) is calculated as:
SI = (ΔY / Y) / (ΔX / X)
Where:
- ΔY is the change in the output variable (Y).
- ΔX is the change in the input variable (X).
- Y is the original output value.
- X is the original input value.
