Analysis of Variance and Covariance
1983This chapter concerns linear models of the form $$ y = X\beta + e $$ with e ~ N(0, σ 2 Iwhere y and e are random vectors of length N, X is an N × p matrix of constants, s is a vector of p parameters and I is the unit matrix. These models differ from the regression models of the previous chapter in that X, called the design matrix, consists ...
