Abstract :
The confidence region and the related confidence level are the bases for the uncertainty expression in a measurement process. In this work, a multivariate model is considered, and different situations with respect to the parameters constituting the model are examined. Computational results are reported and analyzed to assess the validity of the proposed approach.
