Solving Least Squares Problems.
Journal ArticleDOI
Correlation and Causation.
Robert F. Ling,David A. Kenny +1 more
TL;DR: In this paper, the authors present a method of measuring the direct influence along each separate path in a system and thus of finding the degree to which variation of a given effect is determined by each particular cause.
Journal ArticleDOI
Some cautionary notes on the use of principal components regression
Ali S. Hadi,Robert F. Ling +1 more
TL;DR: In this article, the authors show that the principal components regression (PCR) methodology can fail in the sense that when the response variable is regressed on all of the p principal components (PCs), the first (p − 1) PC contributes nothing toward the reduction of the residual sum of squares, yet the last PC alone contributes everything.
Journal ArticleDOI
General Classes of Influence Measures for Multivariate Regression
Bruce E. Barrett,Robert F. Ling +1 more
TL;DR: In this paper, the authors consider the problem of detecting observations that, individually or jointly, exert a disproportionate amount of influence in univariate OLS regression analysis and propose separable leverage and residual components for multiple-case influence.
