How to find error in sobol indices

Hello, everyone! I would like some help to understand some results… I am using a 2d model with six outputs variable. I set uniform distribuitions to the inputs variable using 10% of range around a initial vetor. This print is the output of the sobol analysis. I have made some tests with different sample size, but the answer presents different values, but the same behavior… all the indices have the same value. Could you help me to understand that?


Dear Thamires,

As I understand it, you have 2 input variables and 6 output variables. However, your screenshot shows 8 input variables. Can you check again if you have defined your problem correctly?

Best regards,
