Explicit linear maximum likelihood estimation in mixed models

Wulff, Shaun S. (1999-06-02)

Mixed models have been widely used to model data from experiments which have fixed and random factors. Often there is interest in the estimation of fixed effects and variance components. The likelihood procedure is a g ...
Fisher and logistic discriminant function estimation in the presence of collinearity

O'Donnell, Robert P. (Robert Paul) (1990-09-27)

The relative merits of the Fisher linear discriminant function (Efron, 1975) and logistic regression procedure (Press and Wilson, 1978; McLachlan and Byth, 1979), applied to the two group discrimination problem under ...
Propensity score methodology for nonignorable nonresponse

Starcevich, Leigh Ann H. (2010-09-21)

When data are not missing at random, approaches to reduce nonresponse bias include subsampling nonresponding units and modeling. The objective of this thesis is to develop unbiased and precise model-assisted estimators ...
Uses of Bayesian posterior modes in solving complex estimation problems in statistics

Lin, Lie-fen (1992-03-17)

In Bayesian analysis, means are commonly used to summarize Bayesian posterior distributions. Problems with a large number of parameters often require numerical integrations over many dimensions to obtain means. In thi ...
