[20150623] Nonparametric Bayes approach for a semimechanistic pharmacokinetic and pharmacodynamic model
Both frequentist and Bayesian approaches have been used to characterize population pharmacokinetics and pharmacodynamics(PK/PD) models. These methods focus on estimating the population parameters and assessing the ... 
[20090708] Nonparametric estimation of first passage time distributions in flowgraph models
Statistical flowgraphs represent multistate semiMarkov processes using integral transforms of transition time distributions between adjacent states; these are combined algebraically and inverted to derive parametric ... 
[20150128] On the Equivalence Between the LRT, RLRT and Ftest for Testing Variance Components in the Generalized Splitplot Models
I study the equivalence between the Likelihood Ratio Test (LRT), Restricted Likelihood Ratio Test (RLRT) and the Ftest when testing variance components within the class of generalized splitplot (GSP) models. In this work, ... 
[20150624] OrderConstrained Reference Priors with Implications for Bayesian Isotonic Regression, Analysis of Covariance and Spatial Models
Selecting an appropriate prior distribution is a fundamental issue in Bayesian Statistics. In this dissertation, under the framework provided by Berger and Bernardo, I derive the reference priors for several models which ... 
[20110916] Scan statistics for the online detection of locally anomalous subgraphs
Identifying anomalies in computer networks is a challenging and complex problem. Often, anomalies occur in extremely local areas of the network. Locality is complex in this setting, since we have an underlying graph ... 
[20100209] Stable isotope sourcing using sampling
Stable isotope sourcing is used to estimate proportional contributions of sources to a mixture, such as in the analysis of animal diets, plant nutrient use, geochemistry, pollution, and forensics. We focus on animal ecology ... 
[20140213] A Survey of Lackoffit Tests Based on Sums of Ordered Residuals
Christensen and Lin (2014), henceforth CL, suggested two lackoffit tests to assess the adequacy of a linear model based on partial sums of residuals. In particular, their tests evaluated the adequacy of the mean function. ...
