The analysis of variance report has the annotation turned on by default. It can be toggled on/off by selecting View > Annotated ANOVA. The annotation comments are designed to help determine if the current model explains the observed data.
Check to see that the following conditions are met:
Model F-value and associated p-value confirm model significance.
Predicted R-squared and Adjusted R-squared are in reasonable agreement (within 0.2).
Adequate Precision is sufficiently high (>4).
Tests on individual terms confirm they are significant.
