Table 1 Mean percentage bias (Pbias) and standard deviation (SD) values for the plots used for validation of DBH, height, basal area, and volume, as well as the mean of all four biases

From: Under storm risk, economic productivity of Norway spruce (Picea abies (L.) H. Karst) in monoculture shows sharper decline than in mixture with European beech (Fagus sylvatica L.)
