This situation that the variable under consideration (the target variable) occurs with other variables (co-located variables) arises many times in practice and we want to explore the possibility of improving the prediction of variable Z1 by taking into account the correlation of Z1 with these other variables. For example, the prediction of lead can be improved if we also know the values of zinc...
متن کاملc STATISTICS IN SPACE DIMENSION TWO
We construct as a selfadjoint operator the Schroedinger hamiltonian for a system of N identical particles on a plane, obeying the statistics deened by a representation 1 of the braid group. We use quadratic forms and potential theory, and give details only for the free case; standard arguments provide the extension of our approach to the case of potentials which are small in the sense of forms ...
متن کاملC Taxes , Wages , and the Labor Supply of Older Americans
The aging of the U.S. population, combined with an increasing probability that any given older individual will work, means that the importance of older workers to the labor force is rising. One possible solution to the solvency problems facing the Social Security System is increasing the labor supply of older workers. Understanding how policy levers can affect the labor supply of the elderly th...
متن کاملC*-Extreme Points and C*-Faces oF the Epigraph iF C*-Affine Maps in *-Rings
Abstract. In this paper, we define the notion of C*-affine maps in the unital *-rings and we investigate the C*-extreme points of the graph and epigraph of such maps. We show that for a C*-convex map f on a unital *-ring R satisfying the positive square root axiom with an additional condition, the graph of f is a C*-face of the epigraph of f. Moreover, we prove som...

An object belonging to a class is a of if it does not belong to any subclass of . An object is a of a class if it is a direct member of or is a direct member of some subclass of . One of the advantages of object-oriented data models [BM93] compared to other data models is that they support a direct representation of real-world domains. These models directly represent the structure and behavior ...
