**Appendix C**

This appendix supplements Section 3.5 by viewing the *p*(*α*∗) (i.e., significance of the estimated *α*<sup>∗</sup> value), *p*(*β*∗) (i.e., significance of the estimated *β*<sup>∗</sup> value) and (*R*2) <sup>∗</sup> (i.e., the adjusted R square value) of the SLR models in Table 5 from another perspective. Tables 4, A3 and A5 re-sort the results by the transform method applied on the RHS independent variable in each SLR model. For each specific transform, the results for all pairs of variables are aggregated and summarised for clearer inspections.

The results are provided directly without any further marks for inspections. In addition, the order of the sub tables, from (a) to (h), follows the same order in Tables 3, 6 and 7 for the different transformation method.
