The analysis of variance (ANOVA) presented in Table 3 offers a detailed statistical evaluation of the second-order polynomial model developed to predict the centric efficiency factor (ξγ) as a function of the footing spacing ratio (S/B) and the load eccentricity ratio (e/B).The overall model is highly significant, with a very high F-value of 127.59 and a p-value < 0.0001, indicating that the selected regression equation reliably explains a substantial portion of the variability in the response variable.
