Abstract:
|
Multivariate Gaussian copula models driven by sparse or factor vector autoregressions are studied. The focus is on such models of large dimensions and for observations taking integer values. Computationally efficient estimation methods based on covariances and their relationships involving Hermite expansions are introduced and examined, both numerically on synthetic and real data, and from a theoretical standpoint.
