SAFE Toolbox

The SAFE Toolbox provides a set of functions to perform Global Sensitivity Analysis in a Matlab/Octave environment. It implements several methods, including the Elementary Effects Test, Regional Sensitivity Analysis, Variance-Based (Sobol') sensitivity analysis, and the novel PAWN method. More information about SAFE and how to apply for download can be obtained from the SAFE website:

The modular structure of SAFE allows the user to easily plug in and out other Matlab/Octave functions and facilitates the integration of numerical models running under a different computing environment.
