Multiple deletion measures and conditional influence in regression model.
Communications in Statistics - Theory and Methods, 29(11) pp. 2391–2404.
The joint effect of the deletion of the ith and jih cases is given by Gray and Ling (1984), they discussed the influence measures for influential subsets in linear regression analysis. The present paper is concerned with multiple sets of deletion measures in the linear regression model. In particular we are interested in the effects of the jointly and conditional influence analysis for the detection of two influential subsets.
