Influence analysis of linear models with random effects. (English) Zbl 0943.62069
Summary: A unified diagnostic method for linear models with random effects based upon the joint likelihood given by G.K. Robinson [Stat. Sci. 6, No. 1, 15-51 (1991)] is presented. The case deletion model is equivalent to the mean shift outlier model, as well as case weights model. From this point of view, several new diagnostic measures, such as Cook distance, \(WK\) diagnostics are derived. Some previous results are improved. Numerical examples illustrate the method.
