The influence of statistical and narrative evidence on consumer search for additional product information
(University of Missouri--Columbia, 2014)
The purpose of this 2 X 2, between-subjects experiment is to use the model of Information Search Process (ISP) to test the effects of two common message features used in electronic word-of-mouth: statistical valence (positive/negative) and narrative...
Bayesian methods on selected topics
(University of Missouri--Columbia, 2012)
Bayesian methods are widely adopted nowadays in statistical analysis. It is especially useful for the statistical inference of complex models or hierarchical models, for which the frequentist methods are usually difficult to be applied. Though as a...
Verifying risk-based inspection intervals based on historical records and statistical analysis of bridge files
(University of Missouri--Columbia, 2014)
Speed-based safety analysis for work zones
(University of Missouri--Columbia, 2011)
is usually considered as the measures of effectiveness in evaluating speed management strategies. In order to determine the significance of the improvements of the measure of effectiveness, statistical methodology is applied. However, in spite of the wide use...
Statistical and stochastic results for three dimensional fluids
(University of Missouri--Columbia, 2012)
In part I, we show that the longitudinal correlation function for homogeneous and isotropic turbulence remains negative in an interval of time, up to Galerkin approximation. Part II covers the existence and uniqueness of ...
Objective Bayesian inference for stress-strength models and Bayesian ANOVA
(University of Missouri--Columbia, 2012)
First of all, for estimating the reliabilities in Weibull stress-strength models, some matching priors are derived based on a modi ed pro le likelihood. Simulation studies show that these matching priors perform well with ...
Regression analysis of clustered interval-censored failure time data
(University of Missouri--Columbia, 2012)
Clustered failure time data occur when the failure times of interest are clustered into small groups, while interval censoring occurs when the event of interest cannot be observed directly and is only known to have occurred ...
Statistical analysis of length-biased and right-censored data
(University of Missouri--Columbia, 2013)
methods for both nonparametric and semiparametric estimations. In this thesis, we will exploit these unique aspects and discuss the statistical analysis of length-biased and right-censored data. The first part of this dissertation discusses a goodness...
Statistical image analysis of photoactivated localization microscopy
(University of Missouri--Columbia, 2013)
. In this study, we used statistical method to analyze the images of photoactived localization microscopy. The 2D guassian fitting was used to obtain the centriod of each fluorescent molecule. The Ripley K value was calculated to measure the association...
An evaluation of the Missouri public high school personal finance course graduation requirement : is there a transfer of knowledge?
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This researcher performed an evaluation of the Missouri public high school personal finance graduation requirement. Sophomore, junior, and senior students at a Missouri public...
Hierarchical modeling of nonlinear multivariate spatio-temporal dynamical systems in the presence of uncertainty
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Dynamic spatio-temporal models are statistical models that specify the joint distribution of a spatio-temporal process as the product of a series of conditional models whereby...
Bayesian analysis for detecting differentially expressed genes from RNA-seq data
(University of Missouri--Columbia, 2014)
characteristic curves. Finally, the analyses of three publicly available RNA-Seq datasets demonstrate the power and flexibility of the hmmSeq methodology. This dissertation also introduces an empirical Bayesian approach to detect differentially expressed genes...
Integrate template matching and statistical modeling for continuous speech recognition
(University of Missouri--Columbia, 2011)
In this dissertation, a novel approach of integrating template matching with statistical modeling is proposed to improve continuous speech recognition. Commonly used Hidden Markov Models (HMMs) are ineffective in modeling details of speech temporal...
The relationship between 2013-2015 Missouri public school district student performance and district expenditures and statistics
(University of Missouri--Columbia, 2016)
The purpose of this quantitative study was to create a predictive model to account for the variance in student performance based upon school district categorical expenditures. The study analyzed seven independent variables, ...
Statistical model-based methods for observation selection in wireless sensor networks and for feature selection in classification
(University of Missouri--Columbia, 2012)
We apply statistical model-based approaches to address temporal and spatial observation selection challenges in wireless sensor networks. For temporal observation selection, we present an improved version of VoIDP algorithm that is the first optimal...
Some topics in multi-regional clinical trials and meta-analysis using Bayesian models
(University of Missouri--Columbia, 2017)
meta-analysis using only summary statistics. For MRCTs, one key issue is how to assess the consistency of treatment effect among concerned regions and how to determine the sample sizes. Two frequentist consistency criteria defined by the guideline...
Bayesian partition model for identifying hypo- and hyper- methylation
(University of Missouri--Columbia, 2017)
is to test the methylation difference under two conditions of biological samples. However, the high cost and complexity of this sequencing experiment limits the number of biological replicates, which brings challenges to the development of statistical methods...
On hydrodynamic equations and their relation to kinetic theory and statistical mechanics
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] We establish conditions on the Hamiltonian evolution of interacting molecules that imply hydrodynamic equations at the limit of infinitely many molecules ...
Analysis of host-pathogen interactions via clustering, statistical analysis, and data visualization
(University of Missouri--Columbia, 2015)
Infectious diseases are caused by a variety of agents: viruses, bacteria, parasites, or even proteins. Using existing state-of-the-art methods and tools I developed myself, I studied aspects of infectious agents. To find ...
Forecasting county-level unemployment accounting for spatial correlation
(University of Missouri--Columbia, 2011)
measures, correlation statistics, and Moran's I, which is the most commonly used measure of spatial association. The effects of counties being similar in nature are also considered. Following these analyses, regression models are estimated that predict...
