Increased corporate, government and academic demand has prompted official statistics to release individual respondent data (microdata) in addition to the traditional tabular data. Microdata must be masked by a statistical disclosure control (SDC) method before being published, because otherwise the statistical confidentiality of respondents would be compromised. A novel application of watermark...

Multidimensionality in Statistical, OLAP, and Scientific Databases 47 Copyright © 2003, Idea Group Inc. Copying or distributing in print or electronic forms without written permission of Idea Group Inc. is prohibited. INTRODUCTION AND BACKGROUND There is a lot of data that can be viewed as multidimensional data. The term multidimensional databases typically refers to a collection of objects, ea...

Chin proposed an audit scheme for inference control in statistical databases (SDBs) which can determine whether or not a query will lead to the compromise of an SDB. As Chin points out that the dynamic updates of an SDB are prohibited in this scheme because, otherwise, the time and storage requirements will become infinite. The restriction limits the use of this scheme since many SDBs need to b...

The development of fisheries in the oceans, and other human drivers such as climate warming, have led to changes in species abundance, assemblages, trophic interactions, and ultimately in the functioning of marine food webs. Here, using a trophodynamic approach and global databases of catches and life history traits of marine species, we tested the hypothesis that anthropogenic ecological impac...

Gene class, ontology, or pathway testing analysis has become increasingly popular in microarray data analysis. Such approaches allow the integration of gene annotation databases, such as Gene Ontology and KEGG Pathway, to formally test for subtle but coordinated changes at a system level. Higher power in gene class testing is gained by combining weak signals from a number of individual genes in...

BACKGROUND The Apgar score is used worldwide for assessing the clinical condition and short-term prognosis of newborn infants. Evidence for a relationship with long-term educational outcomes is conflicting. We investigated whether Apgar score at 5 min after birth was associated with additional support needs (ASN) and educational attainment. METHODS Data on pregnancy, delivery and later educat...

The present study sought to define neighborhood context by examining relationships among data from city-level administrative databases at the level of the census block group. The present neighborhood investigation included 1,801 block groups comprising a large, northeastern metropolitan area. Common factor analyses and multistage, hierarchical cluster analyses yielded two dimensions (i.e., Soci...

This paper addresses the following question: “how do we fit statistical models efficiently with very large data sets that reside in databases?” Nowadays it is quite common to we encounter a situation where a very large data set is stored in a database, yet the statistical analysis is performed with a separate piece of software such as R. Usually it does not make much sense and in some cases it ...
