In the present paper we study quasi-Monte Carlo rules for approximating integrals over $d$-dimensional unit cube functions from weighted Sobolev spaces of regularity one. While properties these are well understood anchored spaces, this is not case ANOVA which another very important type reference rules. Using a direct approach provide formula worst error spaces. As consequence bound above in te...

To standardize the tea export market and guarantee interest of consumers, adulteration problem in Taiping Houkui should be eliminated. In this study, a screening scheme comprising chemometrics statistical analysis was proposed to estimate geographical origin tea. A total 11 metal ions were detected by performing chemometric experiment. The key variables that can used identify screened using lea...

Multinomial logistic regression is preferred in the classification of multicategory response data for its ease interpretation and ability to identify associated input variables each category. However, identifying important high-dimensional poses several challenges as majority are unnecessary discriminating categories. Frequently used techniques include regularisation such Least Absolute Selecti...
