Hi Anita,

You may want to use SimulationSensitivityAnalysis:

Objet : [ot-users] directional sampling - mean point in event domain + importance factors

 

Hi all,

I am using Directional Sampling in OpenTURNS.

In the documentation, it is specified that it is not possible to get the mean point in event domain and the importance factors through the class SimulationResults (as for Monte Carlo). Why?

By looking at the DirectionalSampling.cxx file, I can see that the computation of the mean point in event domain is commented out:

      // meanPointInEventDomain = meanPointInEventDomain + computeMeanContribution(roots) * direction;

      ++contributionNumber;

    } // if contribution

  }

  // meanPointInEventDomain = meanPointInEventDomain * (1.0 / contributionNumber);

Why? Is there a way to calculate them?

Thank you,

Anita
