Pairwise and global dependence in trivariate copula models
MetadataShow full item record
We investigate whether pairwise dependence properties related to all the bivariate margins of a trivariate copula imply the corresponding trivariate dependence property. The main finding is that, in general, information about the pairwise dependence is not sufficient to infer some aspects of global dependence. In essence, dependence is a multi-facet property that cannot be easily reduced to simplest cases.

Joint and conditional dependence modelling of district heating demand and weather conditions: a copula-based approach Di Lascio FML; Menapace A; Righetti M (LMU Munich, 2019)We analyze the dependence relationship between district heating demand and weather conditions, such as outdoor temperature and solar radiation, through copula function. Copula function makes it possible to represent complex ...
Joint and conditional dependence modelling of peak district heating demand and outdoor temperature: a copula-based approach Di Lascio FML; Menapace A; Righetti M (2020)This paper examines the complex dependence between peak district heating demand and outdoor temperature. Our aim is to provide the probability law of heat demand given extreme weather conditions, and derive useful implications ...
Durante, F (Springer, 2013)Tail dependence is an important property of a joint distribution function that has a huge impact on the determination of risky quantities associated to a stochastic model (Value-at-Risk, for instance). Here we aim at ...
