4. Discussion and Conclusion
Results show that for each industry section, the CV of TE for the samples
obtained using the proposed methodology do not exceed the target value of
5% (Table 2). Specifically, the maximum CV for the samples obtained using the
proposed methodology is 0.0504 observed at section I or Accommodation
and Food Service Activities and 20.3618 observed at section M or Professional,
Scientific, and Technical Activities for the original samples. Further, the results
show that for the original samples, seven (7) out of the eighteen (18) PSIC
sections do not fall within the target CV of 5% while none does not fall above
5% for the samples obtained using the proposed methodology.
The distribution of samples in Table 2 also shows that the samples were
distributed with respect to the size of the PSIC section. It is known that section
C or Manufacturing section has the highest number of division and
subsections among the other sections. Correspondingly, the computed
percentage of samples obtained from the LH algorithm for the said section
was the highest (12.38%). This is followed by section G or Wholesale and Retail
Trade (9.85%) and section N or Administrative and Support Services (9.54%).
The distribution of the CV of TE for each subsection was plotted by section
as shown in Figure 1. The results show that for all sections, the corresponding
CV of TE per subsection does not exceed the target value of 5%. Although
there are outliers present, their corresponding values still reside within the
target CV.
