Hi, I am interested in running sensitivity analysis (variance-based). But instead of running Monte Carlo simulations in R, I already have my sample data in two tables. So how do I run Sobol on my own data then? Does that mean that the model null? And then to use tell()? I cannot find any examples online to follow. I would appreciate it if some one can point me to an example like this in R. Many thanks, om [[alternative HTML version deleted]]
