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
