DF—Total Degrees of Freedom; Adj. SS—Adjusted Sum of Squares; Adj. MS—Adjusted Mean Squares; The F-value is the test statistic used to determine whether the term is associated with the response; The p-value is a probability that measures the evidence against the null hypothesis. Lower probabilities provide stronger evidence against the null hypothesis. 95% significant values are given in bold.
