Python sjc copula
WebMay 3, 2024 · Copulas allow us to decompose a joint probability distribution into their marginals (which by definition have no correlation) and a function which couples (hence the name) them together and thus allows us to specify the correlation seperately. The copula is that coupling function. WebCopula - Multivariate joint distribution.
