  1. DF degree of freedom, adj SS adjusted sum of squares, adj MS adjusted mean of squares
  2. The analysis of variance (ANOVA) was applied at 95% confidence intervals, variables and models would be statistically considerable at levels of significance, P-value < 0.05
  3. Lack-of-Fit value is non-significant
