Fig. 3From: Allometric models for estimating aboveground biomass in the tropical woodlands of Ghana, West AfricaInfluence of dbh classes on model accuracy and precision. The model of Chave et al. (2014) is included here as a reference model. The influence of the dbh classes on the model bias of the various models (M1–M7) are compared with the reference model (Chave et al. 2014)Back to article page
