Table 1.

Orderings of proposed methods in terms of both ARE and PSAE. ARE, average relative error; PSAE, proportion of yielding estimates with smallest absolute error among 500 runs; MD, median approach; ME, mean approach; LS, least squares; RLS, robust least squares; POI, poisson approach. RPOI, robust least squares when measurement errors depend on dilution levels;
