Zastosowanie głębi lokacyjnej i regresyjnej w analizie poziomu zanieczyszczenia środowiska w Polsce

In the paper the comparison of the level of environment pollution in voivodships was conducted for Poland before and after the accession to the European Union. The measures of location and regression depth were used in the analysis. The classification of voivodships was conducted using the multivariate median. The usage of the multivariate median was also proposed in analysis of structural changes of phenomenon in time. The regression coefficients were estimated by the deepest regression method in order to eliminate the influence of outliers.
