This thesis examines issues related to Valiant's Probably Approximately Correct (PAC) model for learning from examples. In this model, a student observes examples that consist of sample points drawn according to a fixed, ...

This thesis deals with the asymptotic behavior of stopping rules ${\rm T\sb{A}}$ and ${\rm T\sb{d}}$ proposed by Martinsek (Ann. Statist., 12 (1984):533-550). The asymptotic normality of these stopping rules, when A tends ...

Two different methods for comparing alternative mixed models describing the continuous variable underlying all-none response traits were proposed. The first may be viewed as an extension of the analysis of deviance using ...

This thesis main focus are the robustness properties of the Schwarz Information Criterion (SIC) based on sample objective functions defining (Bias) robust M-estimators. The Bayesian underpinnings of such a criterion are ...

It was the purpose of this study, through the use of a Monte Carlo simulation, to investigate the robustness of the analysis of covariance (ANCOVA) model relative to violations of some of the model's assumptions, and to ...

Efron (1988) proposes the use of standard logistic regression techniques to estimate hazard rates and survival curves from survival data. These techniques allow statisticians to use parametric regression modeling on survival ...
