Sensitivity analysis helps identify which model inputs convey the most uncertainty to the model output. One of the most authoritative measures in global sensitivity analysis is the Sobol’ total-order index, which can be computed with several different estimators. Although previous comparisons exist, it is hard to know which estimator performs best since the results are contingent on the benchmark setting defined by the analyst (the sampling method, the distribution of the model inputs, the… Expand

A flexible ‘metafunction’ framework to benchmarking is introduced which randomly generates test problems of varying dimensionality and functional form using random combinations of plausible basis functions, and a range of sample sizes. Expand
A simple and efficient method for global sensitivity analysis based on cumulative distribution functions
A novel GSA method, called PAWN, to efficiently compute density-based sensitivity indices, which is to characterise output distributions by their Cumulative Distribution Functions (CDF), which are easier to derive than PDFs. Expand

Distribution-based sensitivity analysis from a generic input-output sample
An alternative approximation procedure is presented that makes PAWN applicable to a generic sample of inputs and outputs while requiring only one tuning parameter and allows the user to estimate PAWN indices as complementary metrics in multi-method GSA applications without additional computational cost.

Sensitivity analysis of a sensitivity analysis: We are likely overlooking the impact of distributional assumptions
Although uncertainty in input factor distributions is known to affect sensitivity analysis (SA) results, a standard procedure to quantify its impact is not available. We addressed this problem byExpand
