This might be a silly question, but I'm confused why ANOVA is different from a panel data model, with dummy variables for group, and inference on the coefficients on the dummy variables. Is this what ANOVA is? Am I missing something important about ANOVA? Thanks for your help.

Realized that this is a duplicate: Why is ANOVA taught / used as if it is a different research methodology compared to linear regression?
