Modelling Lorenz curves (LC) for stochastic dominance comparisons is central to the analysis of income distribution. It is conventional to use non-parametric statistics based on empirical income cumulants which are in the construction of LC and other related second-order dominance criteria. However, although attractive because of its simplicity and its apparent flexibility, this approach suffer...

Outliers can be particularly hard to detect, creating bias and inconsistency in the semi-parametric estimates. In this paper, we use Monte Carlo simulations demonstrate that methods, such as matching, are biased presence of outliers. Bad good leverage point outliers considered. Bias arises case bad points because they completely change distribution metrics used define counterfactuals; points, o...

in more recent years, it has become increasingly recognized that r&d; (research and development) is a key driver of economic growth, a source of innovation and change, and as such stimulates improvements in productivity and economic competitiveness. it is closely associated with knowledge and flexibility, two factors that have gained new significance as a source of competitiveness in an increas...

Non-stationarity is ubiquitous in human behavior and addressing it the contextual bandits challenging. Several works have addressed problem by investigating semi-parametric warned that ignoring non-stationarity could harm performances. Another prevalent social interaction which has become available a form of network or graph structure. As result, graph-based received much attention. In this pap...
