Compositional Tables Analysis in Coordinates

Compositional tables – a continuous counterpart to the contingency tables – carry relative information about relationships between row and column factors; thus, for their analysis, only ratios between cells of a table are informative. Consequently, the standard Euclidean geometry should be replaced by the Aitchison geometry on the simplex that enables decomposition of the table into its independent and interactive parts. The aim of the paper is to find interpretable coordinate representation for independent and interaction tables (in sense of balances and odds ratios of cells, respectively), where further statistical processing of compositional tables can be performed. Theoretical results are applied to real‐world problems from a health survey and in macroeconomics.     

Chi-Squared Goodness-of-Fit Tests for Parametric Accelerated Failure Time Models

We give chi-squared goodness-of fit tests for parametric regression models such as accelerated failure time, proportional hazards, generalized proportional hazards, frailty models, transformation models, and models with cross-effects of survival functions. Random right censored data are used. Choice of random grouping intervals as data functions is considered.     

Sustainable Development of Maritime Tourism in Croatia 2007–2015

This paper’s objective has been an analysis of the sustainable development of Croatia’s maritime tourism. In order to define the main characteristics and determinants of the maritime tourism, a model of growth has been used. The evaluation and analysis of the relevant variables and the resulting growth rates have been aimed at a scientific formulation of the results of the sustainable development analysis of the maritime tourism in the Republic of Croatia. Combinations of a number of scientific methods have been used, among which the most relevant are statistical and mathematical methods, method of model drawing, analysis and synthesis, induction and deduction. The basic hypothesis has been confirmed through the direct growth rates of the chosen model variables. It has been confirmed that, based on scientific insights into the sustainable development of the maritime tourism, it is possible to suggest a new model of its sustainable development in Croatia for the period 2007–2015.
