This paper considers the growth experience of the South African economy during 1970-1994, against the background of the international convergence phenomenon affirmed by Daumol (1986). Convergence refers to the idea that countries with initially low real per capita income tend to grow faster than wealthier countries, and that their per capita income levels and growth rates will eventually reach a common end-state. This empirically observed catching-up process by the developing countries is assisted by their economic restructuring. Here the growth performance of the South African economy is compared with some established and newly industrialised countries, using statistical dispersion and distance measures.

ABSTRACT This study aimed to test the application of the technique of support vector machines (SVM) to estimate the volume of eucalyptus trees. The data used in this study were from of 2307 trees of clonal hybrids (Eucalyptus grandis x Eucalyptus urophylla) located in southern Bahia. In the definition of stratification traditionally used 53 stratums were defined (defined by the stratification project and clone). He set the model of Schumacher and Hall for each stratum. The SVM were constructed to correlate the volume of trees on the basis of other independent variables which may be numeric as dbh and height and categorical as genetic material and design. The estimates were analyzed using statistical and graphical analysis of residues. The analysis consisted of the graphical inspection statistical dispersion of errors (residuals) in relation to the percentage of the values observed, and the analysis of the histogram of residues. The statistics used were the correlation between the observed and estimated volumes. The model of Schumacher and Hall showed the correlation between observed and predicted values of 0,993, and the SVM set of correlated 0,994. The SVM technology showed good adaptation to the problem, and this can use to predict the volumetric production of planted forests.
