Purpose: The main aim of this paper is to present a concept marginal vertical income convergence. This method allows determine the individual contribution objects (countries, regions) observed general process real Design/Methodology/Approach: Proposed methodology avoid limitations classical analysis To check cross-country stability parameters and assess an convergence process, separate regressi...

The aim of this work is studying the use of copulas and vines in numerical optimization with Estimation of Distribution Algorithms (EDAs). Two EDAs built around the multivariate product and normal copulas, and other two based on pair-copula decomposition of vine models are studied. We analyze empirically the effect of both marginal distributions and dependence structure in order to show that bo...

Recurrent event analysis has been a topic that has generated much attention in the last few years. The analysis of recurrent event data can be a complex task, with many different relationships and dependencies that need to be specified. One aspect of recurrent events that is difficult to specify, and even more complex to justify, is the relationship a subject’s rate of failure will have as even...

This paper gives identification and estimation results for marginal effects in nonlinear panel models. We find that linear fixed effects estimators are not consistent, due in part to marginal effects not being identified. We derive bounds for marginal effects and show that they can tighten rapidly as the number of time series observations grows. We also show in numerical calculations that the b...

background. this study evaluated the effect of two prophylaxis techniques on the marginal gap of ci v resin-modified glass-ionomer restorations. methods. standard cl v cavities were prepared on the buccal surfaces of 48 sound bovine mandibular incisors in this in vitro study. after restoration of the cavities with gc fuji ii lc resin-modified glass-ionomer, the samples were randomly assigned to...
