Table 7 AIC, MSD and p-values of NLME models tested for estimating sapling annual height increments of spruce, fir and beech, V* = Vjk from the equation \( \Delta {H}_{ijk} = a_{j} \times {H}_{ijk}^{(b_{jk} + c_{j}V_{jk})} \times {O}_{k}^{d_{j}} + \epsilon _{ijk} \), where ΔHijk = sapling annual height increment for an individual i of species j on plot k, as a function of sapling height (Hijk), canopy openness (Ok) and a climate variable (Vjk)
