Comparison of linear mixed effects model and generalized model of the tree height-diameter relationship
height function mean height Michailoff function Norway spruce mean diameter uniform height curve
2015/11/26
Models of height curves generated using a linear mixed effects model and generalized model were compared. Both tested models were also compared with local models of height curves, which were fitted us...
Generalized additive models as an alternative approach to the modelling of the tree height-diameter relationship
nonparametric method Norway spruce Petterson function
2015/7/2
Generalized additive models were tested using three types of smoothing functions as an alternative for
modelling the height curve. The models were produced for 23 forest stands of Norway spruce (Pic...
