Testing fixed effects in mixed linear models

Creator:

Rady, El-Houssainy Abdelbar

Abstract:

This dissertation is concerned with hypothesis testing for fixed effects in mixed linear models. Our primary emphasis is on mixed models when the class of covariance matrices has what we call a rich linear structure. Such models include mixed ANOVA models and regression models with heteroscedastic variances. For the majority...

On admissibility among affine sets of linear estimators

Creator:

Pereira, Clifford Brian

Abstract:

We describe a general finite-dimensional inner product space setting for studying the characterization of admissible linear estimators. We extend the results of LaMotte (1982) and derive necessary and sufficient conditions for an estimator to be admissible among an arbitrary affine set of linear estimators when they are compared using quadratic...
