Table 5 AIC, MSD and p-values of NLME models tested for estimating sapling densities of spruce, fir and beech, V* = Vjk from the equation \(\protect \phantom {\dot {i}\!} N_{ijk} = a_{j} \times e^{(b_{jk} H_{ijk})} \times e^{(c_{j} V_{jk})} + \epsilon _{ijk} \), where Nijk = sapling densities for height class i of species j on plot k, as a function of sapling height (Hijk) and a climate variable (Vjk)
