Multiple Imputation for Measurement Error Correction Based on a Calibration Sample.

Guo, Ying - 2010

In much of applied statistics variables of interest are measured with error. In particular, regression with covariates that are subject to measurement error requires adjustment to avoid biased estimates and invalid inference. We consider two aspects of this problem. Detection Limits (DL) arise...

Statistical Inverse Problems on Graphs with Application to Flow Volume Estimation in Computer Networks.

Singhal, Harsh - 2009

Estimation of flow volumes in computer networks involves the use of data that are either highly aggregated or fairly noisy. We address several conceptual and practical aspects of the use of such data for flow volume estimation in this work. The results presented are often of general statistical...

A Scaled Linear Mixed Model for Multiple Outcomes

Lin, Xihong; Ryan, Louise; Sammel, Mary; Zhang, Daowen; … - 2000

We propose a scaled linear mixed model to assess the effects of exposure and other covariates on multiple continuous outcomes. The most general form of the model allows a different exposure effect for each outcome. An important special case is a model that represents the exposure effects using a...

Two Stochastic Multidimensional Choice Models for Marketing Research

Carroll, J. Douglas; Soete, Geert; DeSarbo, Wayne S. - 1990

Two recently developed probabilistic multidimensional models for analyzing pairwise choice data are introduced, discussed in terms of their differential properties, and extended in several ways. The first one, the wandering vector model, was originally suggested by Carroll [12] and extended by...

Missing Covariates in Longitudinal Data with Informative Dropouts: Bias Analysis and Inference

Roy, Jason; Lin, Xihong - 2005

We consider estimation in generalized linear mixed models (GLMM) for longitudinal data with informative dropouts. At the time a unit drops out, time-varying covariates are often unobserved in addition to the missing outcome. However, existing informative dropout models typically require...

An evaluation of parsimony for microbial risk assessment models

Soller, Jeffrey A.; Eisenberg, Joseph N. S. - 2008

Microbial risk assessment (MRA) is a process that evaluates the likelihood of adverse human health effects following exposure to a medium in which pathogens are present. Several different classes of models are available to quantitatively characterize risks to human health from exposure to...

Semiparametric Analysis of Recurrent Events Data in the Presence of Dependent Censoring

Ghosh, Debashis; Lin, D. Y. - 2003

Dependent censoring occurs in longitudinal studies of recurrent events when the censoring time depends on the potentially unobserved recurrent event times. To perform regression analysis in this setting, we propose a semiparametric joint model that formulates the marginal distributions of the...
