Book recommendations for parametric regression and regression diagnostics

[Jummeth]

Hi,

I hope this is the correct section, I am looking for a good starting book about Parametric Regression and Regression Diagnostics.

I am currently slogging through "Semi-Parametric regression" Ruppert et-al (2003) and I'd like a slightly easier book that goes slightly more slowly and with more explanations on Linear Regression.

Thanks muchly in advance.

A standard book is Greene's "Econometric Analysis", or easier, "Econometric Methods" by Jonhston and DInardo.
I know those, unfortunately, they are quite expensive.
