I have a very basic understanding of R and stat so my question may sound very simple. I am trying to do a sensitivity analysis on a model that takes 30+ input parameters. The model is created in R.
From my understanding, if I want to use sobolo2002 - my input should be X1 and X2.
How do I generate X1 and X2 for my model?
From what I have read - my initial task would be to determine the range and distribution for each input variable and generate sample points form the distribution of the inputs. The model will be fed with the sample elements and a set of output is produced. These model evaluations are then used as a basis for SA.
Is this the case for sobol2002 as well?
I did read the answer here to understand sobol package in R
but I still have trouble understanding how to link my input variables in this function.
Any help/hints/idea would be really appreciated.
