SAFE Toolbox

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.

The SAFE Toolbox includes several visualization tools to investigate and effectively communicate GSA results.

All the methods implemented in SAFE comprise a set of functions to assess the convergence and robustness of the sensitivity indices.

Comprehensive documentation is embedded in the code throughout comments and a set of workflow scripts to get started.

The SAFE Toolbox provides a set of functions to perform Global Sensitivity Analysis in 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.

The SAFE Toolbox was developed by Francesca Pianosi, Fanny Sarrazin and Thorsten Wagener at the Department of Civil Engineering of University of Bristol. A general introduction to the rationale and architecture of SAFE is given in:
