GOF Analysis/Discussion

What actions constitute an analysis of goodness-of-fit for a regression model?

What are the typical graphical displays used in this analysis of goodness-of-fit?

Why do we assess the goodness-of-fit of a regression model?

What can go wrong in the interpretation of the results and the use of a regression model that would be deemed to “fit poorly”?

these seem like a bunch of test or homework questions :(

What part don't you understand in particular? Also, what type of regression model are you referring to?
