Sobol First order and total sensitivities

2 views (last 30 days)
I have 19 input variables and two outputs. I am focusing on one at a time. I have a closed form model flike Y = F(x1, x2, x3.... x19) for example so the function values can be computed almost instantly oncethe input vector X is known. I am using some program GSAT frome File exchange. However, I realizedthe number of combinations it has to compute is way too high like 500,000+ or so. My program has been running already more than a day and I am not sure what is going on. The same program worked fine when I had 9 inputs (511 combinations) and a simple model and result came out like less than an hour. My question is, whether I am doing something fundamentally wrong and there might be a better way or not? please help. Thanks in advance.

I understand what you are saying. My problem is perhaps too big to handle for a PC at home. But I needed an independant confirmation which you gave. Thanks. But let us see for more answers and if anyone else have any ideas.
