This essay distinguishes several different kinds of measures of information from each other, noting that differences between them show that our pretheoretical concept of information is multiply ambiguous. Incremental information, conditional information, transmitted information, expected information, and deductive information are discussed. Ten…

This publication presents estimates of drug-related emergency department (ED) episodes from the Drug Abuse Warning Network (DAWN) from 1994 through the first half of 2001. DAWN is an ongoing, national data system that collects information on drug-related visits to EDs from a national probability sample of hospitals. This publication marks a major…

To use the concept of probability and uncertainty estimation is a common practice in daily life. To assist students in learning the fundamentals of probability and statistics, not through the usual class and note taking, a group-learning and practical "statistical system" was designed. By connecting with the main statistical center, students not…

This study compared the accuracy of predicting two-group membership obtained from K-means clustering with those derived from linear probability modeling, linear discriminant function, and logistic regression under various data properties. Multivariate normally distributed populations were simulated based on combinations of population proportions,…

The present study is concerned with the retention of single-cue probability learning (SPL) tasks with scaled cue and criterion varibles. (Author)

In line with the latent trait model, the continuous response level is defined and considered, in contrast to the discrete response levels, which have already been explored by the author. (Editor)

Unlike previous studies, the present experiments simultaneously differentiated the stimulus events along more than one (binary) dimension. (Authors)

A method for introducing ideas of probability theory is presented. The method is illustrated by solving a coin tossing" problem. (FL)
