Abstract

In this work we consider a linear programming approach for finding the parameters of an interval quadratic regression model. We propose also for interval quadratic regression model a linear-fractional programming approach as well as a stochastic programming with chance-constraints approach. We discuss also, a fuzzy regression model of quadratic type for which we give an interval regression simplification.
