How to Fit a Response Surface?
The contour plot and the response surface representation of the regression
The contour plot and the response surface are visualized in Figure 9 & Figure 10, respectively. The comfort level increases as the temperature increase. However, the effect of humidity is not as obvious as the temperature as the estimated effect is 50% (1.5) as compared to the temperature (3). Moreover, near straight lines shows very little interaction between the temperature and the humidity to affect the human comfort.
