Table 3. Comparing Site-Level ANC-RT with and without Continuation from ANC-UAT Sites.

Mean difference and MAE (Mean Absolute Error) between estimated and “true” value of quantities. Results given for each data scenario at 1, 3, and 5 years of simulated ANC-RT data. Each setting (of data scenario and year) uses 50 replicates under different seeds.
