2 unusual facts about Additive function


Variance-based sensitivity analysis

Variance-based measures of sensitivity are attractive because they measure sensitivity across the whole input space (i.e. it is a global method), they can deal with nonlinear responses, and they can measure the effect of interactions in non-additive systems.

due to the fact that the interaction effect between e.g. Xi and Xj is counted in both STi and STj In fact, the sum of the STi will only be equal to 1 when the model is purely additive.
