Regression Analysis

The focus of the text is on thinking clearly about and solving practical statistical problems. The approach leads from the theoretical (meaning conceptual not mathematical) to the applied, with the concept being that samples (theory) tell the investigator what needs to be known about populations (application). The authors stress regression in practice and assume that a population has a finite number of elements, which is always the case in real problems.
