"Multivariate Statistical Analysis of Hydrochemical and Radiological Data of Serbian Spa Waters," Journal of Geochemical Exploration, Vol. 112, pp. 226-234. Description: Spa water properties from 30 sites in Serbia. Data were pre-processed with Box-Cox transformations before analysis with PCA and cluster analysis. Water was taken from 4 geological structures: 1=Hydrological Basin 2=Karstic terrains 3=Volcanogen Massifs 4=Metamorphic Regions Variables/Names Location id (idNum) Water Source (waterSource) Temperature (tempCels) pH (pH) Electrical Conductivity (elecCond) Total Solids (totSolid) Ca2 concentration (Ca2) Mg2 " (Mg2) Na " (Na) K " (K) Cl " (Cl) SO2 " (SO2) HCO " (HCO) SiO " (SiO) Geological Structure (geoStruct)
