Presentation Transcript

  1. Including error correlations K. Thomsen, EFDA CSU-Garching • Using the Pantula program to study the effect of error correlations • Large ELMy Std. dataset (IAEA2004S=1) of DB3v13F • The PCEIV (EVOR) method used on engineering variable set (W, I, B…) gives a result that is different from using it on the ‘Kadomtsev variables’ ( WR-1/2, IR1/4, BR5/4… St. Petersburg, Russia, 3 - 6 October 2005

  2. Assumed errors (%) St. Petersburg, Russia, 3 - 6 October 2005

  3. Error correlations are important The correlations between the errors of B and R; n and a; A and a have not been included above St. Petersburg, Russia, 3 - 6 October 2005

  4. Error correlations are important The correlations between the errors of B and R (-0.87); n and a (-0.58); A and a (0.62) have been included above St. Petersburg, Russia, 3 - 6 October 2005

  5. Conclusion • If the errors on the variables are correlated the PCEIV (evor) is not the tool to use St. Petersburg, Russia, 3 - 6 October 2005
