Using results from copula theory, we show that the composition effect naturally has an interesting structure that can be exploited in empirical applications. What are copulas in English?¶ 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.

Another easy solution, if your kernel is appropriate (goes to 0 at infinity such as a Gaussian, Matèrn or Exponential kernel), is to set a threshold under which your covariance is set to zero and to use a sparse representation for the covariance matrix (you can even be more extreme and set a fixed number of entry to be non-zero giving you a fixed memory use).
