Compound Poisson distributions (CPD's) are frequently used as alternatives in studying situations where a simple Poisson model is found inadequate to describe. In this paper an attempt is made to identify compound Poisson distributions when it is known that the conditional distribution of two...

The paper discusses extensions of the well-known hypergeometric and negative hypergeometric distributions for describing data with multiple counts. The derivation of these extensions is based on certain urn schemes that allow for sampling clusters of items rather than individual items. The...

The Shewhart, Bonferroni-adjustment and analysis of means (ANOM) control chart are typically applied to monitor the mean of a quality characteristic. The Shewhart and Bonferroni procedure are utilized to recognize special causes in production process, where the control limits are constructed by...

We provide a comprehensive and critical review of the h-index and its most important modifications proposed in the literature, as well as of other similar indicators measuring research output and impact. Extensions of some of these indices are presented and illustrated.

The EWMA control chart is used to detect small shifts in a process. It has been shown that, for certain values of the smoothing parameter, the EWMA chart for the mean is robust to non normality. In this article, we examine the case of non normality in the EWMA charts for the dispersion. It is...

Autoregressive Conditional Heteroskedasticity (ARCH) models have been applied in modeling the relation between conditional variance and asset risk premium. The most important theoretical regularities that govern the dynamic structure of financial time series are presented. A model named...

In 1997 the Greek Government introduced a law by which the assessment of the students in Greek Lyceums (High Schools) changed. According to the new law the assessment of the 10th and the 11th grade students is based, for the first time, not only on their in school performance as assessed by...

Sumo wrestling is a traditional fighting sport in Japan and has been popular since the 18th century (the Edo period). Using a data set for all sumo wrestlers in the post-World War II period, this paper investigates how wrestlers’ body mass index (BMI) is associated with their win rate and...

The great Hanshin-Awaji (Kobe) earthquake, which occurred in 1995, resulted in tremendous economic damage to the city of Kobe. Using individual-level data of Japan during the period 2000–08, I investigated the long-term impact of the earthquake on the happiness of surviving victims. After...

The Japanese General Social Survey was used to determine how individual preferences for income redistribution are affected by family structure, such as the number of siblings and birth order where individuals grow up. After controlling for various individual characteristics, the important...
