Table 3 Details of trials used for model validation showing actual and predicted mean outerwood density for each trial. The slopes of linear regression models between actual and predicted wood densities within each trial, along with their 95 % confidence intervals. The overall slope is derived from a model fitted to the combined data with separate intercepts for each trial and a common slope parameter
From: Modelling the effects of genetic improvement on radiata pine wood density
