A distinction between two classes of problems used in laboratory studies of judgment and inference phenomena is made. The distinction is relevant to both single-cue probability learning and multiple cue probability learning within the linear lens model paradigm. (Author/JKS)

In this paper, the author gives a review of the literature on complex multivariate distributions. Some new results on these distributions are also given. Finally, the author discusses the applications of the complex multivariate distributions in the area of the inference on multiple time series. (Author)

Considers the problem of risk-equivalence of two statistical procedures for statistical decision problems. The crucial argument is based on rewriting risk-equivalence in terms of Choquet's integral representation theorem. It is shown that for certain special cases that do not fulfill the assumptions of the Main Theorem, risk-equivalence holds at…

Proposes a probabilistic mechanism to describe various forms of the Bradford phenomenon reported in bibliographic research. The inclusion of a time parameter in the model to allow predictions of dynamic systems is explained. (58 references) (CLB)

The purpose of this paper is to calculate the upper limit of the correlation between normal and dichotomous variables. An empirically obtained correlation should be evaluated in view of this limit, instead of the usual limit of Pearson correlation. (Author)

Investigated the effects of different types of risk information in a simulated decision-making task to test the predictions of protection motivation theory. College students (N=226) completed the task. Results showed outcome severity, efficacy of protection, and access to protection were related to protective decisions. (BH)

The fact that a group may subdivide into smaller subgroups is examined in the light of probability theory. (Author)

The characteristic shape of the normal distribution, one hump and two tails, is discussed. The reasoning is based on variation, combinations, probability, and logarithms. The purpose is to be able to answer some of the "whys" students might ask. (LS)

The Wilcoxon two-sample test used to examine judge bias. (MM)

A computational short cut suggested by Feldman and Klinger for the one-sided Fisher-Yates exact test is clarified and is extended to the calculation of probability values for certain two-sided tests when sample sizes are unequal. (Author)
