- Abstract:
- The present work exposes the comparison among numerical methods used in the calibration of a set of high accuracy weights by subdivision method. This paper covers the comparison of the mean values, the uncertainties and correlations obtained with the Orthogonal, the Gauss Markov, the Ordinary Least Squares and the Weighted Least Squares (Lagrange Multiplier) methods. These methods are the most commonly used in the realization of the mass scale in the National Metrology Institutes (NMI). Also, the uncertainty evaluated by these methods was compared against the evaluation by a numerical simulation method (Monte Carlo’s method).
