FunctionalChaosSobolIndices

class FunctionalChaosSobolIndices(*args)

Sensitivity analysis based on functional chaos expansion.

Available constructors:

FunctionalChaosSobolIndices(functionalChaosResult)

Parameters:

functionalChaosResult : FunctionalChaosResult

A functional chaos result resulting from a polynomial chaos decomposition.

Notes

This structure is created from a FunctionalChaosResult in order to evaluate the Sobol indices associated to the polynomial chaos decomposition of the model.
