ear models with parameter restrictions are identified as special general ridge estimators. This is based
on a decomposition result for admissible estimators and on the characterization of linearly sufficient and
admissible estimators in unrestricted models given in Markiewicz (1995).
and Phrases: Admissibility, linear sufficiency, partial parameter restrictions, general ridgeestimator, mean squared error function.
