(1994)This thesis contains a discussion of three problems related to structural changes and unitroots in timeseries analysis. First, it is shown under which conditions it is possible to consistently estimate the break date in ...

(20150423)This thesis proposes a method to quantitatively measure the resilience of transportation systems using GPS data from taxis. The granularity of the GPS data necessary for this analysis is relatively coarse; it only requires ...

(1991)A theoretical framework is proposed for multivariate quality control based on multivariate statistical analysis and informationtheoretical measures. A flow chart is proposed to determine whether the process is in control ...

(1995)The simultaneous and nonparametric estimation of latent abilities and item characteristic curves is considered. In particular, the joint asymptotic properties of ordinal ability estimation and kernel smoothed nonparametric ...

(1992)A multitude of studies conducted on advance organizer effectiveness during the 19801990 time period were systematically examined, evaluated, and compared to studies carried out prior to 1979. In spite of wide variation ...

(2003)Imprecisely or incompletely observed data often appear in engineering, epidemiology and economic studies, observations on certain variables may be grouped or measured with errors, which poses challenges to the usual ...

(2005)The press releases from the Federal Open Market Committee(FOMC) are one of the major inputs to the interest rate futures market. To estimate the impact associated with the FOMC announcements, the random intervention model ...

(20120206)In order for a machine learning effort to succeed, an appropriate model must be chosen. This is a difficult task in which one must balance flexibility, so that the model can capture the complexities of the domain, and ...

(2000)Five applications were carried out in this study. In Application 1, L1 ultrametrics under fixed constraints were fitted to gene frequency data of CavalliSforza et al. (1994) using both the IRIP approach and a linear ...

(1991)Modern scientific researchers often use complex computer simulation codes for theoretical investigations. We model the response of computer simulation code as the realization of a stochastic process. This approach, design ...

(1990)This thesis consists of two parts. In the first part we study the dynamics and the boundaries between basins of attraction of a logistic map defined in real 2 x 2 matrices. We show how these boundaries are of a mixed type, ...

(2002)A new, rich class of maxent priors for natural images from imprecise subband statistics in multiple orthonormal wavelet bases is developed. Experimental results for the problem of image restoration in additive white Gaussian ...

(1989)A popular nonparametric measure of a monotone relation between two variables is Kendall's tau. Originally, most analysis of this statistic assumed the two variables were independent, while more recently there has been ...

(1993)Several nonparametric tests based on ranks have been proposed to handle analysis of variance problems. But questions have been raised about the appropriateness of some procedures that are mere rank transformations of normal ...

(2001)Third, it has been noticed in image estimation practice that a translation invariant (TI) wavelet transform enhances estimation performance. We analyze the conventional complete wavelet transform and the TI wavelet transform ...

(1996)We first consider convergence in law of measurable processes with a general parameter set and a state space. To this end, we need to investigate topological properties of the space of measurable functions which is the paths ...
