Abstract : This project focused on the development of data analysis and statistical methodology which may be characterized by one or more of the properties that they are large in size, high in dimension, and nonhomogeneous. The major thrust is in visualization on of both point clouds and mathematical structures in high dimensions. The specific advances made under this project are three dimensional generalizations of the Andrews plot, the grand tour in k-dimensions, fast algorithms for the pseudo-Grand Tour and structural inference using ridge estimation.
