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...
A MIXED-EFFECTS MODEL TO ESTIMATE STAND VOLUME BY MEANS OF SMALL FOOTPRINT AIRBORNE LIDAR DATA FOR AN AMERICAN AND A GERMAN STUDY SITE
Mixed-effects models random effects lidar forest inventory stand volume
2015/11/10
Similar datasets (inventory plots, stand maps and lidar data) were available for study sites in the USA and Germany. These datasets are grouped or hierarchical in that several sample plots are located...
Meteorological and trace gas factors affecting the number concentration of atmospheric Aitken (Dp = 50 nm) particles in the continental boundary layer: parameterization using a multivariate mixed effects model

Measurements of aerosol size distribution and different gas and meteorological parameters, made in three polluted sites in Central and Southern Europe: Po Valley, Italy, Melpitz and Hohenpeissenberg i...
Evaluation of Rhodotorula growth on solid substrate via a linear mixed effects model
confidence intervals giant colony growth curves image analysis solid substrate cultivation
2014/2/25
The growth of Rhodotorula glutinis and Rhodotorula mucilaginosa was studied under optimal and stress cultivation conditions at 10°C and 20°C for 14 days. The method of image analysis was used to deter...
Parameter estimates in random intercept mixed effects model for repeated measures
Repeated measures Random effects Convergence system Strong convergence Strong convergence rate
2007/12/11
In this article the following random intercept mixed effects model will be considered: $\ y_{ij}=v_{i}+ x_{ij}^{\tau}\beta+\epsilon_{ij}, i=1,\ldots,m;j=1,2,\ldots, n_{i},$ where $\{v_{i}\}$ are i.i.d...
