    Greetings All,

    I am working with 15 states and 197 transitions and find myself in trouble trying to manually run local sensitivity analyses. Especially because the keystone of this model is interactions, which I am undoubtedly missing when adjusting single inputs.

    A global sensitivity analysis package “sensitivity” was recently released in R. However, I haven’t began to work through how to adapt the model output to R. So I am curious if other scripts exists for ST-SIM and if others have conducted sensitivity analyses on their models.

    Thanks for any comments or directions,
    -Christopher

    The simplest way to conduct a sensivitity analysis with a SyncroSim-based model is to script the analysis using either rsyncrosim (for R) or pysyncrosim (for python). In fact this is one of the major benefits of SyncroSim – the ability to quickly and systematically generate and compare many model “scenarios”. Once you get a sensitivity analysis script running in R or Python then you can visualize the results using either your scripting environment or alternatively through the SyncroSim Windows UI.

    You can find a short video demonstrating this approach on the Getting Started page for the omniscape SyncroSim package . The second video on this page (i.e. the one called “omniscape & rsyncrosim for reproducibility”) demonstrates a very simple sensitivity analysis using rsyncrosim. The same approach can be used for any SyncroSim model package, including for example the ST-Sim Package you are using.
