sensitivity analysis

Mathematics

The varying of parameters in a simulation to discover which parameters have the greatest influence on the features of interest.

Computer

Investigation of the degree to which the behaviour of a system is affected by a change in the value of some (explicit or implicit) parameter or variable, or by a combination of changes. For example, a simple analysis might determine how the performance of a system is impacted by changing the number and sizes of the storage buffers that are allocated to that system.

Economics

1. A method for the assessment of the robustness of predictions of a model to variations in the model assumptions. An example of sensitivity analysis in econometrics is the investigation of the robustness of the significance and of the predicted theoretical sign of the relationship between the dependent variable and each explanatory variable against variations in the set of explanatory variables.
2. A method of assessment of a risky investment project based on a number of possible realizations for the macroeconomic and project-specific factors that determine the value of the project, where in computations the factors are changed one at a time. Typically, three realizations—pessimistic, most likely, and optimistic—are considered for each factor. See also scenario analysis.
