A Study Of Joinpoint Models For Longitudinal Data, Libo Zhou
A Study Of Joinpoint Models For Longitudinal Data, Libo Zhou
UNLV Theses, Dissertations, Professional Papers, and Capstones
In many medical studies, data are collected simultaneously on multiple biomarkers from each individual. Levels of these biomarkers are measured periodically over certain time duration, giving rise to longitudinal trajectories. The subjects under study may also be subject to dropout due to several competing causes, the likelihood of which may be affected by the levels of these biomarkers. In this dissertation, we investigate flexible Bayesian modeling of such data, taking into account any available covariate information as well as possible censoring of the drop-out times. We propose joint models for multiple biomarkers with multiple causes of dropout. Our proposed models …
Arima Models For Bank Failures: Prediction And Comparison, Fangjin Cui
Arima Models For Bank Failures: Prediction And Comparison, Fangjin Cui
UNLV Theses, Dissertations, Professional Papers, and Capstones
The number of bank failures has increased dramatically over the last twenty-two years. A common notion in economics is that some banks can become "too big to fail." Is this still a true statement? What is the relationship, if any, between bank sizes and bank failures? In this thesis, the proposed modeling techniques are applied to real bank failure data from the FDIC. In particular, quarterly data from 1989:Q1 to 2010:Q4 are used in the data analysis, which includes three major parts: 1) pairwise bank failure rate comparisons using the conditional test (Przyborowski and Wilenski, 1940); 2) development of the …
Effects Of Inlet Conditions On Diffuser Outlet Performance, Zaccary A. Poots
Effects Of Inlet Conditions On Diffuser Outlet Performance, Zaccary A. Poots
UNLV Theses, Dissertations, Professional Papers, and Capstones
Building air distribution terminal system designers and system installers require accurate quantitative information on the performance of the installed system to achieve optimum efficiency and levels of human comfort. This requires field installation adjustment values from published ideal pressure loss, air distribution and sound generation installation performance. This study documents the air output performance of different installation configurations of six types of ceiling diffusers and compares the results to performance when installed according to ANSI/ASHRAE Standard 70-2006. A diffuser inlet supply plenum was designed for optimum flow and used to acquire a baseline set of data covering the six types …
Poisson Process Monitoring, Test And Comparison, Qing Chen
Poisson Process Monitoring, Test And Comparison, Qing Chen
UNLV Theses, Dissertations, Professional Papers, and Capstones
The task of determining whether a sudden change occurred in the generative parameters of a time series generates application in many areas. In this thesis, we aim at monitoring the change-point of a Poisson process by method, which is characterized by a forward-backward testing algorithm and several overall error control mechanisms. With the application of this proposed method, we declare that Mount Etna is not a simple Poissonian volcano, because two different regimes divided by the change point, January 30th 1974, are identified. The validation procedures, used in a complementary fashion, by the formal hypothesis tests and graphical method will …
