Dynamic Hierarchical Factor Models [PDF]

open access: yesSSRN Electronic Journal, 2011
AbstractThis paper uses multilevel factor models to characterize within- and between-block variations as well as idiosyncratic noise in large dynamic panels. Block-level shocks are distinguished from genuinely common shocks, and the estimated block-level factors are easy to interpret. The framework achieves dimension reduction and yet explicitly allows

Hierarchical models as marginals of hierarchical models

open access: yesInternational Journal of Approximate Reasoning, 2017
We investigate the representation of hierarchical models in terms of marginals of other hierarchical models with smaller interactions. We focus on binary variables and marginals of pairwise interaction models whose hidden variables are conditionally independent given the visible variables. In this case the problem is equivalent to the representation of

Hierarchical Cont-Bouchaud model [PDF]

open access: yes, 2015
We extend the well-known Cont-Bouchaud model to include a hierarchical topology of agent's interactions. The influence of hierarchy on system dynamics is investigated by two models. The first one is based on a multi-level, nested Erdos-Renyi random graph
