We look at fitting regression models using data from stratified cluster samples when the strata may depend in some way on the observed responses within clusters. One important subclass of examples is that of family studies in genetic epidemiology, where the probability of selecting a family into...

Statistical tests based on the scan statistic are introduced for detecting possible increases in the occurrence of hospital events. The tests use a moving window and the theoretical aspects of the tests are investigated using Markov chain theory. The main objective of this study is to provide a...

Many statistical forecast systems are available to interested users. To be useful for decision making, these systems must be based on evidence of underlying mechanisms. Once causal connections between the mechanism and its statistical manifestation have been firmly established, the forecasts...

On a typical day, more than 53 million tons of goods valued at about $36 million are moved on the US multimodal transportation network. An efficient freight transportation industry is the key in facilitating the required movement of raw materials and finished products. Among different modes of...

The dissertation develops a comprehensive theoretical framework which concerns the impact of institutional framework on economic performance at the micro and macro level. After extensively examining the existing literature, the conception of firm-government network relations and strategic...

Currently the network centric operation and network centric warfare have generated a new area of research focused on determining how hierarchical organizations composed by human beings and machines make decisions over collaborative environments. One of the most stressful scenarios for these...

Fraud and manipulation in prediction markets are systematic results of incentive incompatibility, which, if present, have to be detected and balanced. "Manipulations in Prediction Markets" gives a critical insight into manipulations that are most likely to occur in prediction markets. In a...
