Comparative analysis of algorithms for evaluating key comparison data in the presence of linear drift of a transfer standard
The comparative analysis is provided for three algorithms for key comparison data evaluation in case of linear drift of a traveling measurement standard. The conditions when the third algorithm results in smaller uncertainty associated with the slope. It is shown that under some simplifying assumptions the first two algorithms provide smaller uncertainty associated with the degree of equivalence. The conditions at which third algorithm provides smaller uncertainty associated with the slope are given.
