Herkkyysanalyysi, often translated as sensitivity analysis, is a technique used in modeling and simulation to determine how the uncertainty in the output of a model can be attributed to different sources of uncertainty in its inputs. It helps understand which input variables have the most significant impact on the model's results. This is crucial for identifying key parameters that require more precise estimation or for understanding the robustness of a model's predictions.

The process typically involves systematically varying the input parameters within their defined ranges and observing the resulting changes in the model's output. This can be done through various methods, ranging from simple one-at-a-time variations to more complex global methods like Monte Carlo simulations or variance-based approaches. The goal is to quantify the relationship between input variations and output variability.

Applications of herkkyysanalyysi are widespread across many disciplines, including engineering, environmental science, economics, and risk assessment. For example, in climate modeling, it helps identify which factors most influence temperature projections. In financial risk management, it can reveal which economic variables are most sensitive to changes in market conditions. By highlighting critical parameters, herkkyysanalyysi enables researchers and decision-makers to focus their efforts, improve model accuracy, and make more informed judgments.
