Large datasets are increasingly widespread in many disciplines. The exponential growth of data requires the development more analysis methods order to process information efficiently. In better visualize data, such as Principal Component Analysis (PCA) and MultiDimensional Scaling (MDS) allow extract a low-dimensional structure from high-dimensional set. proposed approach, called Topological (T...

A principal component analysis based on the generalized Gini correlation index is proposed (Gini PCA). The PCA generalizes standard variance. It shown, in Gaussian case, that equivalent to PCA. also proven dimensionality reduction matrix, relies city-block distances, robust outliers. Monte Carlo simulations and an application cars data (with outliers) show robustness of provide different interp...

The ACM/SIGGRAPH Symposia on Solid Modeling and Applications provide an international forum for the exchange of recent research and practical results in all areas and applications of solid modeling. These symposia bring together prominent researchers, practitioners, and numerous students in the field. The sixth ACM Symposium on Solid Modeling and Applications was held in Ann Arbor, Michigan on ...

We consider a rank-based technique for estimating GARCH model parameters, some of which are scale transformations of conventional GARCH parameters. The estimators are obtained by minimizing a rank-based residual dispersion function similar to the one given in Jaeckel (1972). They are useful for GARCH order selection and preliminary estimation. We give a limiting distribution for the rank estima...

phosphosulfonic acid (psa) was found to be an efficient catalyst for the one-pot three-component hantzsch condensation reaction of arylaldehydes, ethylacetoacetate and ammonium acetate to afford the corresponding 1,4-dihydropyridine and polyhydroquinoline derivatives in high yields. psa was also applied for the one-pot preparation of polyhydroquinolines via four-component reaction of arylaldehy...
