Knowing Your Inaccuracy

Insertion only (DS < 0)

• How can the accuracy of a simulation result be assessed if the simulation is inaccurate?

• Compare to precision calculation where simulation data (variance) are used to provide confidence limits

• Consider most-likely inaccuracy for HS insertion

• Postulate dDA ~ (MeDS)-1 for continuous distributions

  • evaluate DA accuracy using simulation DS

• But simulation gives ‘incorrect’ DS

  • generally, simulation DS < true DS (e-DS(sim) > e-DS(true))
  • thus ‘incorrect’ DS indicates larger error
  • safe estimate of inaccuracy
  • gives (probabilistic) upper bound of DA inaccuracy
