[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
