Celem artykułu jest porównanie zastosowania trzech metod wyznaczających przybliżone granice warstw: metody Daleniusa i Hodgesa, Eckmana oraz Mahalanobisa do uzyskania startowych parametrów dla algorytmu optymalizującego stratyfikację przy pomocy metody Schneebergera. Wnioski te można uogólnić na wspomniane metody wyznaczania granic warstw.

The paper contains the studies on the aspect of a choice of initial point in optimal stratification algorithm using the Schneeberger method. This algorithm for finding the optimal strata boundaries requires some initial values, i.e. strata boundaries. In the paper three methods of finding the approximate boundaries are presented, i.e. the method of Dalenius and Hodges, Eckman and Mahalanobis. The strata boundaries got by applying these methods were used as initial parameters in the algorithm of optimal stratification using the method of Schneeberger. The numerical experiment was carried out using the data from the Agricultural Census 2002 regarding the cereals and potatoes area. The best results were obtained using the Eckman and Mahalanobis methods. The results of the most popular method of finding the approximate strata boundaries, i.e. the Dalenius and Hodges method, were rather less satisfying than the results of the two above mentioned methods.
