Symbolic computation of the Duggal transform

Following the results of cite{Med}, regarding the Aluthge transform of polynomial matrices, the symbolic computation of the Duggal transform of a polynomial matrix $A$ is developed in this paper, using the polar decomposition and the singular value decomposition of $A$. Thereat, the polynomial singular value decomposition method is utilized, which is an iterative algorithm with numerical charac...

Graduating the age-specific fertility pattern using Support Vector Machines

A topic of interest in demographic literature is the graduation of the age-specific fertility pattern. A classical graduation technique extensively used by demographers is to fit parametric models that accurately reproduce it. Standard non parametric statistical methodology, as kernels and splines, might alternately be used for this graduation purpose. Support Vector Machines (SVM) is an innova...
