%X <p>With developing possibilities to analyse data automatically there is a need to develop the mathematical and statistical practices for calculations. The article presents the basis about the growth of trees and the existing models of growth, the basics on growth functions,   and the construction of a regression model to analysis the growth. The theoretical model development has been tested with three existing data sets.</p><p>The analysis of growth should be considered with dynamic models. The model need to take into account various aspects and growth factors. The model should have practical implications.</p><p>The PDF contains a summary in German. </p>
