Autocorrelation offsets zero-inflation in models of tropical saplings density

O. Flores, V. Rossi and F. Mortier

Ecological Modelling, 2009, vol. 220, issue 15, 1797-1809

Abstract: Modelling the local density of tropical saplings can provide insights into the ecological processes that drive species regeneration and thereby help predict population recovery after disturbance. Yet, few studies have addressed the challenging issues in autocorrelation and zero-inflation of local density. This paper presents Hierarchical Bayesian Modelling (HBM) of sapling density that includes these two features. Special attention is devoted to variable selection, model estimation and comparison.
