The aim of this paper is to propose a novel approach to integrate financial information, incorporating the dependence structure among the variables. The approach is based on two types of graphical models: vines and non parametric Bayesian belief nets (NPBBNs). Vines are undirected graphs, representing pair copula constructions, which are used to model the dependence structure of a set of variab...

As the ancestor of cultivated grape, Vitis vinifera subsp. sylvestris represents a unique, invaluable genetic resource for the improvement of cultivated grapevines. Recently, five populations of wild grapevines were identified in Portugal. Sixty vines were characterized with 11 nuclear SSR markers and further compared with 70 genotypes of Portuguese Vitis vinifera subsp. sativa. The obtained da...

Background. Grapevine leafroll disease is one of the most widespread viral diseases in vineyards, affecting nearly all grape and wine regions in the world. Infection causes yield losses, ripening delays, and alters fruit chemistry, including lowering soluble solids and increasing titratable acidity. The viruses associated with leafroll disease are transmitted through propagation of infected mat...

More than 100 years ago a grapevine disease of unknown etiology was recognized in France and California, where it was called “folletage” (Ravaz, 1898) and “sunstroke” respectively (Anonymous, 1895). In both cases the disorder was considered to be due to a physiological condition resulting from what was called “abrupt changes in the bottom water level.” Research on the pathological nature of the...

We present a new methodology for selecting a Bayesian network for continuous data outside the widely used class of multivariate normal distributions. The use of bivariate copula densities to model connections between pairs of nodes in the network brings in flexibility in the choice of the distribution. Cand D-vines play a central role in dealing with the high-dimensional aspect of the data, due...
