Robust diagnostic regression analysis

Anthony Atkinson, Marco Riani

"The authors develop new, highly informative graphs for the analysis of regression data including generalized linear models. The graphs lead to the detection of model inadequacies, which may be systematic - perhaps a transformation of the data is needed - or there may be several outliers. These are identified, and their importance is established. Improved models can then be fitted and checked. The graphs are generated from a robust forward search through the data, which orders the observations by their closeness to the assumed model.". "The four main chapters cover regression, transformations of data in regression, nonlinear least squares, and generalized linear models. As well as illustrating their new procedures the authors develop the theory of the models used, particularly for generalized linear models. Exercises with solutions are given for these chapters. The book could thus...
