Abstract
Three algorithms are compared for evaluating the data from key comparisons with linear drift in the value of the comparison standard (use of weighted least squares and two modifications of it). If some simplifying assumptions are met, the first two algorithms produce less uncertainty in the degree of equivalence. Conditions are defined under which the third algorithm provides less uncertainty in estimating the slope coefficient.
