Lehmann (1983) discusses the problem of marginal equivariant estimation of the parameters of a location-scale model. We develop the procedure of simultaneous equivariant estimation and obtain some results. The vector minimum risk equivariant (MRE) estimator is characterized under certain conditions. By considering quadratic type loss function, a characterization and also the uniqueness of the vector MRE is obtained. Four illustrative examples are included.
Dr Chandrasekar received his Ph.D. from the University of Poona under the guidance of Professor B.K. Kale. He is presently a Professor in the Department of Statistics at Loyola College, University of Madras in India. His main research interests are in the areas of Theory of Estimation and Estimating Functions, with a minor interest in Reliability. Dr Chandrasekar is visiting our department for two months.
