Abstract.    This paper considers simultaneous estimation of means from several strata under error-in-variables superpopulation models. Necessary and sufficient conditions for an estimator to be admissible in the class of linear estimators are obtained.

Key words and phrases:    Error-in-variables superpopulation models, mean vector of strata, admissibility, linear estimator.
