Table 1 List of models tested to explain the relationship between harvesting intensity and changes in structural diversity (FSI-change)

From: Assessing the influence of harvesting intensities on structural diversity of forests in south-west Germany

Acronym Model Package Explanation
loess loess stats in addition to simply smoothing a curve, the R loess function can be used to impute missing data points
lm linear model stats lm is used to fit linear models
glm generalized linear model stats produces a generalized linear model for the relationship between HI and change in structural diversity (FSI)
gam generalized additive model mgcv produces a generalized additive model for the relationship between HI and change in structural diversity (FSI)
RF randomForest randomForest implements Breiman’s random forest algorithm for classification and regression (for harvesting classes)
HC harvesting classes No package needed Harvesting classes for 10%-intervals, referred to the standing volume at NFI2002 to generate boxplots
