|---|
| Anna Chunovkina, Maurice Cox |
- Abstract:
- The evaluation of key comparison data is discussed, the general case of correlated data being considered. Particular attention is paid to a simplified procedure for data evaluation, founded on a mixture of distributions associated with the results from the institutes participating in the comparison. The suggested approach uses the model of an interlaboratory experiment from ISO 5725 and uncertainty evaluation in accordance with the Guide to the Expression of Uncertainty in Measurement.
