Some Statistical Approximation based on Post-Widder operators
Keywords:exact error estimation, Voronovskaya-type result, approximation estimate, over convergence phenomenon, Real and complex Post-Widder type operator
In the present paper, we study the convergence of real and modified Post-Widder operators in C, which is known as the extension of approximation of these operators from the real axis in the complex plane. In this direction, we also investigate error estimation in simultaneous approximation and a Voronovskaya-type asymptotic formula.
