               <dc:description>In this paper we deal with the identification of dependencies between time series of equity returns. Marginal distribution functions are assumed to be known, and a bivariate chi-square test of fit is applied in a fully parametric copula approach. Several families of copulas are fitted and compared with Spanish stock market data. The results show that the t-copula generally outperforms other dependence structures, and highlight the difficulty in adjusting a significant number of bivariate data series</dc:description>
               <dc:description>- En aquest article tracta amb la identificació de dependències entre sèries temporals de rendiments d'accions. Les distribucions marginals se suposen conegudes, i un test ji-quadrat bivariant s'aplica dins d'un enfocament totalment paramètric. Diverses famílies de còpules són ajustades i comparades amb dades de la borsa espanyola. Els resultats mostren que la t-còpula generalment supera altres estructures de dependència, i destaca la dificultat d¿ajustar un nombre significant de sèries temporals bivariants.</dc:description>
