Abstract We find new classes of exact solutions for the Einstein-Maxwell field equations. The solutions are obtained by considering charged anisotropic matter with a linear equation of state consistent with quark stars. The field equations are integrated by specifying forms for the measure of anisotropy and one of the gravitational potentials which are physically reasonable. A general feature of our models is that isotropic pressures are regained when certain parameters vanish; this behaviou...

DEVELOPMENT OF STATISTICAL PROGRAM FOR DISCRIMINANT ANALYSIS FOR MIXED VARIABLES USING R-CODE, By Iwuagwu, Chukwuma E. Ibegbulem, Zebulon O. Nwosu, Obinna M. Ekwuribe, Celestine. Department of Statistics, Abia State Polytechnic, Aba, Abia State. Abstract Discriminant analysis is a statistical technique that tried to predict on the bases of one or more independent variables. Whether an individual or other objects can be placed into a particular category of a categorical dependent variables. T...
