Covariances from categorical variables are defined using a regular simplex expression for categories. The method follows the variance definition by Gini, and it gives the covaria...
A fast and simple algorithm for approximately calculating the principal components (PCs) of a data set and so reducing its dimensionality is described. This Simple Principal Compo...
In this paper we consider the problem of automatically generating test suites associated with web-based enterprise systems. In particular, we discuss the construction of a tool de...
