On approximation measures for functional dependencies
Information Systems, 2004We examine the issue of how to measure the degree to which a functional dependency (FD) is approximate. The primary motivation lies in the fact that approximate FDs represent potentially interesting patterns existent in a table. Their discovery is a valuable data mining problem.

Measurement of the severity of amphetamine dependence
Addiction, 1993AbstractA Severity of Amphetamine Dependence Questionnaire (SAmDQ) was administered to 101 subjects attending an Australian drug dependency treatment centre. The SAmDQ was adapted from the Severity of Opiate and Alcohol Dependence Questionnaires (SODQ & SADQ).

Natural resource abundance, resource industry dependence and economic green growth in China
, 2020Analyzing the effect of natural resources on economic green growth and its mechanism of transmission has important reference value for China's economic green growth transformation. Based on the statistical data of 30 provinces in China from 2003 to 2016,

Child factor in measurement dependability
American Journal of Human Biology, 2001AbstractA primary consideration in longitudinal growth studies is the identification of growth from error components. While previous research has considered matters of measurement accuracy and reproducibility in detail, few reports have investigated the errors of measurement due to aspects of the physiology and cooperation of the child.

A measure of dependence indicates in some particular manner how closely the variables X and Y are related; one extreme will include a case of complete linear dependence, and the other extreme will be complete mutual independence. Although it is customary in bivariate data analysis to compute a correlation measure of some sort, one number (or index ...

Dependent Measures and Measurement Systems
2014This chapter describes dependent measures common to conducting research in educational, clinical, and community settings. It explores how to select the most appropriate dependent measures and suggested how to design data collection for applied research studies.

Measurement of Analog Sequential Dependencies
Human Factors: The Journal of the Human Factors and Ergonomics Society, 1964A statistic sensitive to sequential dependencies existing between responses was proposed. Two studies were undertaken to determine the validity and practicality of this measure. In the first study, results included: (1) the distribution of this measure (λ) is sufficiently normal to permit parametric analyses; (2) λ sensitively reflects both individual

This article proposes a new method to estimate an existing mutual information based dependence measure using histogram density estimates. Finding a suitable bin length for histogram is an open problem. We propose a new way of computing the bin length for

The effect of artifacts on dependence measurement in fMRI
Magnetic Resonance Imaging, 2006The study of effective connectivity by means of neuroimaging depends on the measurement of similarity between activity patterns at different locations in the brain, without necessarily presupposing a particular model for this dependence. When these interactions are measured using functional magnetic resonance imaging (fMRI) techniques, however, imaging
