Based on data coding in Section 5.1, multiple linear regression analysis was performed with U-value as the dependent variable and the ratio scale variable of glazing elements, which is expected to have considerable effects on the U-value, as the independent variable [14].
Table 2 gives an example of the ratio scale and the interval scale ([tau] = [kappa] = 8).
As all the evaluation targets had a uniform ratio scale in the range of 0-1, in combination with the contents of extension rank, the classical domain [U.sub.k] of the extension rank k was established, where k=1, 2, 3, 4, 5.
The indicators can be presented on the nominal, sequencing, interval, or ratio scale. In such an environment, the distribution of POIs can be perceived intuitively and the analysis of the POI information will be enhanced through the rational arrangement of adjacent terminals based on scalability and measurements.
Since weights are given by AVERAGE on ratio scales with an arbitrary unit (see Anderson, 1982, Section 2.3.2), the ensuing [G.sub.i] and [L.sub.i] estimates will share a common unit and a common zero, a measurement condition enabling their direct comparison.

Make a series of pairwise comparisons among the elements according to a ratio scale 1, 3, 5, 7 and 9.
In the conventional AHP, the pairwise comparison is commonly made by using a 9-point ratio scale, ranging from least preferred to most preferred.
The AHP process derives priorities using ratio scales, which results in a proportionate and more consistent measure of reality.
For the variables measured with the ratio scale, the following substitution takes place:
Instead, it elicits values on the users' implicit preference function by requiring a numerical pairwise comparison of the criteria on an increasing ratio scale, usually from 1 to 9 (Saaty 1980).
