E-learning plays an important role in education as it supports online education viacomputer networks and provides educational services by utilising information technologies. We present a case study describing the development of an Arabic language elearning course in statistics. Discussed are...

Exploratory factor analysis (EFA) is an important tool in data analyses,particularly in social science. Usually four steps are carried out which contain alarge number of options. One important option is the number of factors and theassociation of variables with a factor. Our tools aim to...

Empirical studies have shown that a large number of financial asset returns exhibit fat tails and are often characterized by volatility clustering and asymmetry. Also revealed as a stylized fact is Long memory or long range dependence in market volatility, with significant impact on pricing and...

Teaching statistics to students in our area of economics and educationalscience often brings about the problem that students have either forgottentheir statistical knowledge, or have taken different classes than the ones weoffer in basic statistics. We therefore need some kind of statistical...

Students of introductory courses consider statistics as particularly difficult,as the understanding of the underlying concepts may require more time andenergy than for other disciplines. For decades statisticians have tried to enhanceunderstanding with the help of technical solutions such as...

Along with many others, we agree that a modern education in statistics needs toincorporate the practical analysis of real datasets, which are usually more complex than the common examples found in standard textbooks. The software used in the teaching of statistics includes standard spreadsheet...

The volatility implied by observed market prices as a function of the strikeand time to maturity form an Implied Volatility Surface (IV S). Practicalapplications require reducing the dimension and characterize its dynamicsthrough a small number of factors. Such dimension reduction is...

In this paper, we present a case study, which describe the development of the Statistic e-learning-course in Arabic language –”Arabic MM*STAT”. The basic frame for this E-book, the system MM*STAT was developed at the School for Business and Economics of Humboldt-Universit¨at zu Berlin....
