Β-RISK IN PROFICIENCY TESTING IN RELATION TO THE NUMBER OF PARTICIPANTS |
---|
Louis-Jean Hollebecq |
- Abstract:
- The Monte Carlo method was applied to PT schemes to investigate their efficiency. Probabilities that the computed z values are over 3 while the true value is less than 2 and that the computed z values are less than 2 while the true values are over 3 are computed for a series of situations: number of participants from 5 to 30, various ratios of repeatability over reproducibility and number of test results per participant, introduction or not of outliers with k from 3 to 10. For each situation, the probabilities of detecting true outliers and to trigger false alerts are discussed.
