We analyze the illicit drug usage by inhabitants and visitors of European cities. Our statistical analyses are by means of linear mixed models. The data on illicit drug usage of cocaine, ecstasy, amphetamines, methamphetamines, and cannabis are collected through wastewater samples from the inlet...

A mixture model incorporating long-term survivors has been adopted in the field of biostatistics where some individuals may never experience the failure event under study. The surviving fractions may be considered as cured. In most applications, the survival times are assumed to be independent....

The relationship between ownership structure and corporate performance might be remarkably strong and in formative within transition economies. In this research, we explore this relationship, referring to the example of the Republic of Serbia. For that purpose, appropriate linear models have...

In Official Statistics, interest in data integration has grown enormously, but the effect of integration procedures on statistical analysis has not yet been sufficiently developed. Data integration is not an error-free procedure and linkage errors, as false links and missed links can invalidate...

Purpose This research aims to explore the impact of an overlooked variable, brand typicality, on brand evaluation and the categorization of counterfeits and imitations. Design/methodology/approach The research design is a 2 × 2 × 2 × 2 mixed design with the first three variables as...

Purpose – Methods and techniques of aggregating preferences or priorities in the analytic hierarchy process (AHP) usually ignore variation or dispersion among experts and are vulnerable to extreme values (generated by particular viewpoints or experts trying to distort the final ranking). The...

In longitudinal studies with subjects measured repeatedly across time, an important problem is how to select a model generating data choosing between a linear regression model and a linear latent growth model. Approaches based both on information criteria and on asymptotic hypothesis test on the...

The relationship between ownership structure and corporate performance might be remarkably strong and in formative within transition economies. In this research, we explore this relationship, referring to the example of the Republic of Serbia. For that purpose, appropriate linear models have...

In order to implement policies against poverty and inequality, policy makers all over Europe should have at their disposal information referring to appropriate domains, since the impossibility to access to goods and services varies with age, gender and zone of residence. However, the major...

An important issue in modelling economic time series is whether key unobserved components representing trends, seasonality and calendar components, are deterministic or evolutive. We address it by applying a recently proposed Bayesian variable selection methodology to an encompassing linear...
