Ocr: A Statistical Model Of Multi-engine Ocr Systems
This thesis is a benchmark performed on three commercial Optical Character Recognition (OCR) engines. The purpose of this benchmark is to characterize the performance of the OCR engines with emphasis on the correlation of errors between each engine. The benchmarks are performed for the evaluation …

A classic statistical model developed towards predicting financial distress
… field of study, despite heavy criticism their models are widely accepted and used. Studies by Grice & Ingram (2001); Grice & Dugan (2001) and Sudarsanam & Taffler (1995) have shown that these models require to be updated regularly with new variables and coefficients due to various factors. This …

Pretest Estimators for the Two Sample Linear Statistical Model
… differ. The two sample heteroscedastic model has received considerable attention recently with the development of a two stage test: one for homoscedasticity followed by a main test for the location parameters. In this context we examine the sampling characteristics of the pretest …

Statistical Model Based Multi-Microphone Speech Processing: Toward Overcoming Mismatch Problem
… will be described with a unified speech model under a generalized expectation maximization (GEM) scheme. From this perspective, multi-microphone optimal speech estimation can be interpreted as pre-processing to increase reliability of feature components before the actual speech …

Contributions to Data Reduction and Statistical Model of Data with Complex Structures
… an emerging need for data reduction, efficient modeling, and model inference. For example, data can contain millions of observations with thousands of features. Traditional methods, such as linear regression or LASSO regression, cannot effectively deal with such a large dataset directly. This …

An Overview and Evaluation of SynthETC: A Statistical Model for Extra-Tropical Cyclones
… over large swaths of area. In this thesis, a statistical model of ETCs, called SynthETC, is discussed. The model accounts for the for genesis, track path, termination, and intensity of statistically generated ETCs. Genesis is modeled as a Poisson process, whose mean is determined by climate …

Statistical model selection techniques for the cox proportional hazards model: a comparative study
… dissertation, common Cox proportional hazards model selection techniques and a random survival forest technique were compared using five performance criteria measures. These performance measures were concordance index, integrated area under the curve, and , and R2 . To carry out this exercise, …

Kinetic theory of piston problem and thermal disturbance by the ellipsoidal statistical model
… to the kinetic theory of gases. The Ellipsoidal Statistical model which gives the correct Prandtl number for a monatomic gas has been solved numerically. Also, the perturbation method proposed by Chu is also applied. Velocity, density, temperature and pressure distributions have been calculated …

The Application of a Statistical Model Investigating Reactive Oxygen Species in Premature Ageing Syndromes
… and ROS buffering ability. This is shown from my statistical modelling of immunofluorescence data showing DNA double strand break repair over time. RD and HGPS fibroblasts showed persistent γ-H2AX foci after DNA damage induction with oxidative stress, yet showed improved repair after induction …

A statistical model relating transcription factor concentrations to positional information in the early Drosophila embryo
… biology, but only recently have quantitative models been proposed that relate measured transcription factor concentrations to enhancer activity. However, successful models are typically computationally time-consuming, thus limiting full exploration and interpretation of the data. This thesis …

A Statistical Model for Seventh-day Adventist White English-Speaking Church Growth in the United States
<p>Problem. Until 1983 there was no statistical model for projecting church growth among white English-speaking Seventh-day Adventist churches in the United States. The purpose of this study was to identify a forecasting model based on the variables that were gathered from pastor and local church …

A Statistical Model to Determine Multiple Binding Sites of a Transcription Factor on DNA Using ChIP-seq Data
… of the genome. In this study we introduce a statistical model to identify multiple binding sites of a transcription factor within a short region of the genome using the ChIP-seq data. Mapped sequence reads from the ChIP-seq experiments are modeled as the sum of observations from unknown …
