Consider the linear model Y=Xβ+e; e~N(0, σ~2I). (1) where X is a known n×p matrix of rank p【n; β∈R^p and σ】0 are parameters. Assume that prior information about β in the form U=Hβ+ε (2) is available. H... Consider the linear model Y=Xβ+e; e~N(0, σ~2I). (1) where X is a known n×p matrix of rank p【n; β∈R^p and σ】0 are parameters. Assume that prior information about β in the form U=Hβ+ε (2) is available. Here H is a known k×p matrix. and H≠0; ε~N(0, W); W is known and positive definite symmetric. Assume also that e and ε are independent. 展开更多
