%description
Estimating height of forest plant is one of the key challenges of recent
times. This package will help to fit and validate AI (Artificial
Intelligence) based machine learning algorithms for estimation of height
of conifer trees based on diameter at breast height as explanatory
variable using algorithm of Paul et al. (2022)
