Forest Growth and Yield Modeling (2011, methodology): “For example, Weiskittel et al. (2007a) found that a mixed model with a correlated error structure and weighting function was a less biased and more precise predictor than a similar model fitted with no random effects, even when the fixed effects were just used for prediction on an independent…”
Modelling annual individual-tree growth and mortality of Scots pine with data obtained at irregular measurement intervals and containing missing observations. (2010, methodology): “…because observed growth and mortality rates must be interpolated to a common length (usually a 1-year or a 5-year growth period), or those growth periods longer (or shorter in the case of the 5-year growth period) than the desired model time interval must be disregarded (Weiskittel et al., 2007).”
Response of branch growth and mortality to silvicultural treatments in coastal Douglas-fir plantations: implications for predicting tree growth. (2007, methodology): “Because the tree growth equations defined height to crown base as lowest live branch (uncompacted crown ratio) (Weiskittel et al., 2007a), each SMC height to crown based was converted to height of lowest live branch (Monleon et al., 2004).”
