In this tutorial, we would be providing a general overview of the various tools in the SEAVEA toolkit with detailed hands- on-experience in variance based sensitivity analysis. The participants would be guided to install the tools on their laptops and conduct sensitivity analysis for models which are currently developed in the SEAVEA project. We can also provide guidance on how to integrate any program that the participants have already developed to the SEAVEA toolkit so that sensitivity analysis can be performed on them. With this tutorial we hope to highlight the utility of sensitivity analysis in dynamical models and make it more accessible to a wider audience. Given its applicability, importance and user-friendliness, we also hope that more research groups will find the tools in the SEAVEA toolkit useful in improving their research capabilities.
