We introduce a Stancu type generalization of the Lupas, operators based on the q-integers, rate of convergence of this modification are obtained by means of the modulus of continuity, Lipschitz class functions and Peetre's K-functional. We will also introduce r-th order generalization of these operators and obtain its statistical approximation properties.
