To make it interpretable, we normalize the Kendall's tau against the baseline to indicate the deviation of cofiring from independence. Figure 14 shows an example of the relative changes in joint firing between FEF and IT neurons, where the… Copulas are used to describe the dependence between random variables. Their name comes from the Latin for "link" or "tie", similar but unrelated to grammatical copulas in linguistics[ citation needed]. For an overview of these copulas, see Nelsen (2006). In finance, copulas are typically applied to derive correlated default probabilities in a portfolio,[ according to whom?] for example in a collateralized debt obligation, CDO. The goal of this paper is to pro- function, we can think about the multivariate gaussian vide simple applications for the practical use of copulas that is a ‘standard’ assumption in risk management. Copulas in general, which include the basic probability version as well as the Lévy and utility varieties, are enjoying a surge of popularity with applications to economics and finance.
Joe [10] and Nelsen [11] are the two comprehensive treatments on copulas. They provide Rivest [19]. We give a brief introduction to Archimedean copulas.
