This empirical study proposes a dependency analysis of monthly financial time series. We use the overlapping technique and non-parametric correlation in order to increase both accuracy and consistency. Copulas are used to test extreme co-movements between financial securities. Our results...

We present a list of challenges one faces when given the task of modeling dependence between stochastic objects, with a special focus on financial applications. Our aim is to draw the readers' attention to common (and not so common) pitfalls and fallacies, and we particularly address readers...

We consider a new copula method for mixed marginals of discrete and continuous random variables. Unlike the Bayesian … methods in the literature, we use maximum likelihood estimation based on closed-form copula functions. We show with a … using data from the 2013 Household Finance Survey, we show how the copula dependence between income (continuous) and …
