Abstract
This paper is a continuation of GGD = Golub, Guttman and Dutter (1973) and DG = Dutter and Guttman (1974a), and will deal with the problem of how to handle outliers in the general univariate linear model situation y = Xθ + ∊, ∊ = N(0, σ2I).when X is not of full rank, and where interest is in the estimation of τ = Bθ, where τ is assumed to be estimable. The special case B = X, that is, interest is in η = Xθ, is discussed.
