McMASTER UNIVERSITY STATISTICS SEMINAR

Week of June 14 - 18, 1999

SPEAKER:	Dr B. Chandrasekar Loyola College, India
TITLE:	"Simultaneous Equivariant Estimation"
DAY:	Tuesday, June 15, 1999
TIME:	10:30 p.m.
PLACE:	BSB-101

SUMMARY

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.
