In the present paper, we study some approximation properties of the Szász type operators involving Charlier polynomials introduced by Varma and Taşdelen in 2012. First, we establish approximation in a Lipschitz type space and weighted approximation theorems for these operators. Then we obtain the error in the approximation of functions having derivatives of bounded variation.

We introduce a spatio-temporal model to represent development of atmospheric pollution in an urban area. An important element this is that recorded measurements are often incomplete which undermines time-series approaches. identify the multiple imputation by chained equation (MICE) method as effective complete data sequences synthetically. Following on from this, we develop vector autoregressiv...
