This book has the following special features:
Use of simple statistical ideas such as linear zero functions and covariance adjustment to explain the fundamental as well as advanced concepts
Emphasis on the statistical interpretation of complex algebraic results
A thorough treatment of the singular linear model, including the case of multivariate response
A unified discussion on models with a partially unknown dispersion matrix, including mixed-
effects/variance-components models and models for spatial and time series data
Insight into updates on the linear model and their connection with diagnostics, design, variable
selection, the Kalman filter, etc.
An extensive discussion on the foundations of linear inference, along with linear alternatives to
least squares
Coverage of other special topics, such as collinearity, stochastic and inequality constraints,
misspecified models, etc.
Simpler proofs of numerous known results
Pointers to current research through examples and exercises
