while CVs of the modified bootstrap 1st stage and design-based ranged from
5.4% to 24.2% (Refer to Figures 1-4). Although, modified bootstrap 2nd stage
is the most precise method, it

is, however, the least accurate method, registering the highest MAPEs in all
quarters (See Figures 5-8). Design-based and modified bootstrap 1st stage are
the most accurate methods in all quarters with trimmed MAPEs ranging from
3.4% to 31.0%, while MAPEs of modified bootstrap 2nd stage ranged from
5.5% to 35.8%.

3.4 Determination of the Best Model
Results for the fourth phase showed that Model 1 has lower dispersion
compared to Models 2 and 3 for both quarters 2 and 3. However, for quarters
1 and 4, dispersion of CVs were lower for Models 2 and 3 (Figures 9-12).
Clearly, the performance of the three models were varied per quarter. The
accuracy of estimates for the three models revealed that Model 1
outperformed the other two models as it consistently yielded estimates with
generally lower MAPE per quarter (Figures 13-16).

4. Discussion and Conclusion
Stratified-LH is the best stratification in terms of precision and accuracy
with PPSSYS and SRSWOR as the best selection method for sample barangays
and sample households, respectively. Twenty (20) sample households seem to
