Marvin H.J. Gruber

An examination of mathematical formulations of ridge-regression-type estimators points to a curious observation: estimators can be derived by both Bayesian and Frequentist methods. In this updated and expanded edition of his 1990 treatise on the subject, Marvin H. J. Gruber presents, compares, and contrasts the development and properties of ridge-type estimators from these two philosophically different points of view. The book is organized into five sections. Part I gives a historical survey of the literature and summarizes basic ideas in matrix theory and statistical decision theory. Part II explores the mathematical relationships between estimators from both Bayesian and Frequentist points of view. Part III considers the efficiency of estimators with and without averaging over a prior distribution. Part IV applies the methods and results discussed in the previous two sections to the Kalman Filter, analysis of variance models, and penalized splines. Part V surveys recent developments in the field. These include efficiencies of ridge-type estimators for loss functions other than squared error loss functions and applications to information geometry. Gruber also includes an updated historical survey and bibliography. With more than 150 exercises, Regression Estimators is a valuable resource for graduate students and professional statisticians.

When Ruby, an artists trespasses into a beautiful garden she is discovered by Ben, the owner. They fall in love and announce their engagement. Ruby finds inspiration for her painting while Ben embarks upon an investigation into the old temple on the lake. But this idyll is soon disrupted by Charlie, Ben's lodger, and George, his gardener. As Ben learns more about former owner Henry Faulkes, and the mysterious temple, it becomes apparent that history may be repeating itself - and that Ruby is not the only person hiding something at Oakstead ...
