Linear algebra and linear models

This monograph provides an introduction to the basic aspects of the theory of linear estimation and that of testing linear hypotheses. The primary objective is to provide a basic knowledge of analysis of linear models to advanced undergraduate or first year Master's students. The second edition virtually covers the same topics as the first edition. Only chapters 4 and 6 have two new sections (4.6) and (6.4), respectively. My comments apply to material in both the old and new editions.
