AB  - The multiple linear regression estimates an average trend of the observed phenomena and so it does not provide a complete illustration of relations among phenomena, while the use of quantile regression gives this aspect. The quantile regression presents the evaluation of regression models of different parts, quantiles of the conditional distribution of some series. The quantile regression is widely used in social policy, in determination of maximal production, consumption analysis, etc. This thesis presents some basic principles and the quantile regression model, which is being estimated by minimization of total absolute deviations using linear programming algorithms. The aim of this thesis is to present how the use of quantile regression provides a more complete understanding of the moving of alcoholic beverages and tobacco consumption (i.e. consumption of luxury goods). The research subject of this thesis is the linear dependence between income and alcoholic beverages and tobacco consumption of 200 households, which were randomly selected from three territories: the city of Belgrade, Central Serbia and Vojvodina in 2010. Based on these data, we estimated simple linear regression and the quantile regression in order to compare their advantages and disadvantages. It was concluded that if the consumption of luxury goods is higher, household income has no effect on the decision about the level of spending.

AB  - The purpose of this study has been to determine the effect of storage on grain quality of three oat cultivars selected in Serbia - Dunav, Vrbas and NS Tara. Freshly harvested oats were stored at the temperature of 25±2°C for 12 and 20 months. There was a significant decrease in the volume mass (458.4 to 408.9 kg/m-3) and the absolute mass of grains (26.6 to 24.2%) during the storage. The germination potential of the grains decreased over time (96.2-94.1%). The changes in the acid degree values (3.77-3.99 ml 1(Na OH/100 g) are highly significant (p lt 0.01). Initially, the pH level of the fresh samples was 6.2, and it decreased to 5.8 after 20 months. Genotypes and volume mass have great effect on storage duration (η2=0.8130 η2 =0.7621 and η2=0.6780). The interaction between the studied factors did not show statistically significant effects on the change in germination of oat grains (p>0.05). What mostly affects an increase in the acid degree value of oat grains is storage duration, followed by a genotype and the interaction between these two factors. The studied oat genotypes show no significant differences in glassiness (p>0.05).
AB  - Ispitivan je uticaj skladištenja na kvalitet i stanje semena ovsa za tri sorte (Dinav, Vrbas i NS Tara) koje su selekcionisane u Srbiji. Sveže požnjeven ovas je uskladisten na 25±2°C na 12 i 20 meseci. Zabeležen je značajan pad vrednosti zapreminske 458.4-408.9 kg m-3 i apsolutne mase 26.6 - 24.2% tokom skladištenja semena ovsa. Sa dužinom vremena skladištenja smanjivalo se biološko svojstvo semena na sposobnost klijavosti 96.2-94.1%. Promene kiselinskog stepena (3.77-3.99 ml 1(Na OH)/100 g) su statistički veoma značajne (p lt 0.01). pH vrednost svežih uzoraka semena je bila 6,2 a nakon 20 meseci 5,8. Dužina skladistenja nije značajno uticala na svojstvo staklavosti. Genotip i zapreminska masa imaju visok uticaja na dužinu skladištenja (η2=0.8130 η2 =0.7621 i η2=0.6780). Interakcija ispitivanih faktora nije ispoljila statistički značajan uticaj na promenu stepena klijavosti semena ovsa (p>0.05). Dužina skladištenja semena ovsa najviše doprinosi porastu vrednosti kiselinskog stepena, a nešto manje genotip, kao i interakcija ovih faktora. Testirani genotipovi ovsa nemaju značajne razlike u pogledu staklavosti semena (p>0.05).
