The aim of the paper was to verify the hypothesis assuming that individual farms, which made use of public funds’ support for investment were more effective than those which had not applied. Stochastic Frontier Analysis and Data Envelopment Analysis were applied to measure the technical effectiveness of individual farms directed at plant production (field crops) in 2004-2006. Return on equity was used as the measure of financial effectiveness. It was established that individual farms which made use of public funds’ support for investment were both technically and financially more effective. Thus the hypothesis was confirmed.

W artykule podjęto problem występowania w zbiorze danych statystycznych obserwacji nietypowych, które mogą wywierać znaczny wpływ na wyniki analizy regresji. Zaprezentowano procedurę statystyczną, która służy ustaleniu czy w zbiorze danych występują obserwacje mające wpływ na rachunek regresji. Następnie na przykładzie danych z rachunkowości rolnej IERiGŻ przedstawiono, jak na równanie regresji wpływa pominięcie obserwacji nietypowych i dokonano analizy dochodowości materialnych czynników produkcji na podstawie oszacowanego modelu regresji.

This article considers the problem of outliers and influential observations that appear in regression analysis and can significantly affect its result. The author presents the statistical procedure, which can be used in order to detect such occurrences in a sample. As a practical example, the author demonstrates, how the elimination of outliers and influential observation would affect on estimation of function of profitability of material factors of production in farms of an economic size between 8 and 40 ESU (basing on the data of agricultural accounting of IERiGŻ).

Unreasonable antibacterial therapy is suspected to be the main reason of emergence of multi-resistant bacteria. The connection between seasonal variability of antibiotic use and reasonable antibacterial therapy has been described. We examined the issue basing on the data obtained from the primary care system in Szczecin (Poland) in order to verify the situation in this region of Central Europe. Increase in antibiotic consumption in a viral infection season was proved to be statistically significant. Statistically significant differences in various drug forms dispensation were also observed. Increased consumption of antibiotics in seasons of influenza-like illnesses might be connected with a lack of proper diagnostics or numerous cases of bacterial co-infections.

Making use of the results of the Common Agricultural Survey of 2002, the economic accounts for agriculture and the results of monitoring of the Polish FADN (2004), the organization as well as the production and income situation of farms operating in the areas of poor conditions for agriculture have been analysed and presented in the article. The interest of such farmers in payments which were available to them in 2004 has been also considered.
