The flexibility of the family of Generalized Lambda Distributions (GLD) has encouraged researchers to fit GLD distributions to datasets in many circumstances. The methods that have been used to obtain GLD fits have also varied. This paper compares, for the first time, the relative qualities of three GLD fitting methods: the method of moments, a method based on percentiles, and a method that use...

This paper presents a “persistent chat” extension to the ePresence Interactive Media webcasting infrastructure to support real-time commenting on and discussing of issues that arise during a learning event, followed by ongoing asynchronous dialogue about these issues while viewing the archives after the event. We report encouraging results of a field study of use of the system by students and a...

The aim of a business statistics course should be to help students think statistically and to interpret and understand data, rather than to focus on mathematical detail and computation. To achieve this students must be thoroughly involved in the learning process, and encouraged to discover for themselves the meaning, importance and relevance of statistical concepts. In this paper we advocate th...

It has been shown that non-determinism, both angelic and demonic, can be encoded in a functional language in different representation of sets. In this paper we see quantum programming as a special kind of non-deterministic programming where negative probabilities are allowed. The point is demonstrated by coding two simple quantum algorithms in Haskell. A monadic style of quantum programming is ...
