Aggregation of isotropic autoregressive fields


This note constitutes a corrigendum to the article of Azomahou (2009), JSPI, 139:25812597. The aggregation of isotropic four nearest neighbors autoregressive models on the lattice Z , with random coefficient, is investigated. The spectral density of the resulting random field is studied in details for a large class of law of the AR coefficient. Depending on… (More)
