I read many articles about clustering using copula. I know that copula is a multivariate function that is used to describe the relationship between variables. However, in clustering we try to group our data into groups. So, my question here, how does copula clustering work? For example, if I have a data with two variables, then by using copula model we can describe the relationship between these two variables, but how we can fit the clustering? Any help with example, please?
