Sensitivity analysis

Definition

Sensitivity analysis is a technique used to determine how different values of an independent variable can impact a particular dependent variable under a given set of assumptions. This method helps identify which variables have the most influence on the outcome of a model or decision-making process, enabling businesses to evaluate risks and opportunities effectively.
