domestic wastewater treatment plants (WWTPs) and full pressure sewerage network. In all variants, the container wastewater treatment plant of daily capacity 450 m3 day-1 was applied. Estimations of investment and exploitation costs for 30 years period operation were performed. Economic multivariate analysis was based on: Payback Period, Dynamic Generation Cost (DGC), Net Present Value (NPV) and Benefit-Cost Ratio (BCR). The obtained indicators were the input data for the weighted sum model allowing to

efficiency to assess the economic sustainability of rural sanitation. Four different variants of rural sanitation, centralized and decentralized, utilizing up-to-date state of art and technologies, were developed and tested with use of NPV, BCR and DGC indicators. The performed multivariate analysis using Weighted Sum Model showed the low profitability of centralized systems of rural sanitation, thus their sustainability may be questioned from economic and social point of view.

individual data aggregation and deals with multivariate analysis of interval- valued, multi-valued and histogram data. The paper discusses the scale effect of MAUP which occurs in a gravity model of population migrations and shows how SDA can deal with this problem. Symbolic interval-valued data was used to determine the economic distance between regions which served as a separation function in the model. The proposed approach revealed that economic disparities in Poland are lower than official

nonreactive eluate (65.4% of 286 eluates performed). A positive DAT was significantly associated with splenectomy (χ2 = 15.4; p < 0.001), elevated IgG levels (χ2 = 26.8; p < 0.001), HCV (χ2 = 20.7; p < 0.001), and warm autoantibody (χ2 = 5.87; p = 0.03). Multivariate analysis revealed that only HCV (OR, 5.0; p = 0.037) and elevated IgG levels (OR, 9.0; p = 0.001) were independently associated with a positive DAT. Alloimmunized thalassemic patients were more likely to have a
