This is to establish the predictive value of the models, since validating the models on the same year they were learned would not have yielded any information about the predictive performance of the models on new unseen data.
It is challenging to provide specific criteria for choosing one set of equations over the other, since validating any biomass equation requires the destructive sampling of multiple stems across a range of diameters.
Since validating the models on unknown data is considered to be more suitable, we prefer to show the performance of our best-performing models, that is, the content-blind impairment-factor-based models for both SD and HD, on the evaluation dataset.
