Students are interested in lecture examples and class exercises involving data connected to the maiden voyage and the sinking of the liner Titanic. Information on the passengers and their fate can be used to explore relationships between various tests for differences in survival rates between...

In the last few years, and especially after the beginning of the economic and financial crisis in Romania, significant changes occurred in the macroeconomic indicators conditioning the final consumption of the population. Consequently, in this article, we aimed at analysing the evolution of the...

A new approach is developed for the automatic (computer based) exploration and analysis of hydrological data, particularly focused on the identification of shifting relationships among hydrological variables. The methodology developed is applicable to many hydrological problems, such as...

En este trabajo se presenta una aportación original en el ámbito del método de valoración conocido como «de las dos betas» (en general método de las dos funciones de distribución), como es sabido, en este método el valor de un activo se establece a través del valor de un índice de...

In the frame of this article, by applying the linear regression model, we proceed to the analysis of the existing dependence between the value recorded by the Bucharest Exchange Trading index (meaning the overall evolution of the capital market in Romania) and that of the stock exchange...

We examine how a statistical test based on discrete spacings between points, in one or more dimensions, detects the regularities in certain popular classes of random number generators. We provide a rule of thumb giving the minimal sample size for the test to reject the generator systematically,...

Most random number generators used in practice are based on linear recurrences, with linear output transformations. This gives long periods, fast implementations, and structures that are easy to analyze. But the points produced by these generators have very regular structures. Nonlinear...

The economic evolutions in Romania, in the first decade of the XXI century, were marked by increases and decreases with rather large amplitudes. Growth period up to 2008 was followed by a significant recession, the economic crisis started in 2009 having implications in the all economic sectors....
