4. Discussion and Conclusion
This study is limited only in using total number of households as an auxiliary
variable in synthetic estimation, it is highly recommended to use other
possible variables that might be related to the variable of interest to verify the
results of this study. The choice of auxiliary variable greatly affects the resulting
estimates of synthetic estimation. Also, the use of other small area estimation
procedures such as composite estimation, empirical Bayes estimation and
hierarchical estimation is recommended in order to arrive at a more reliable
estimate for the total number of farm equipment and facilities in the province
under study. One of these procedures could provide unbiased and more
precise estimates of the selected parameters on ownership of farm equipment
and facilities for the 2002 Census of Agriculture. However, it should be noted
that none particular procedure of estimation will be inevitably consistently
superior for all small areas. Furthermore, any choice of estimator will most
likely result into a loss of precision for some areas as well as gains for others.
