[R] sensitivity analysis with external simulation model - decoupling in package "sensitivity" or alternative?
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I hava a simulation model, of which I want to do a sensitivity analysis. I have identified a number of input variables and my response variable. What I hava done so far: 1) I created a Latin Hypercube with the lhs package (10.000 simulations) 2) simulated these and now I have a data frame with the input parameter and the response variable. I looked around and found the package "sensitivity" which seems to be the most suitable for my case. As the model is not in R, I have to use the decoupling approach. But now I am stuck: How can I do this? An example highlighting how to do the decoupling to do a sensitivity analysis, would be very much appreciated. Alternatively, ids there a different approach I could take? Thanks, Rainer - -- Rainer M. Krug, PhD (Conservation Ecology, SUN), MSc (Conservation Biology, UCT), Dipl. Phys.
