The paper introduces the concepts of ϖ-strongly (resp., ϖ-closure, ϖ-weakly) form of continuous functions on bitopological spaces, furthermore we introduce a theorems, characterizing on the class of functions, show how it can be studied from different point of view.

In this paper, Pareto distribution was studied using a standard Bayes estimator. A Pareto distribution of two parameters is investigated to find the approximation of (M.S.E) of the shape parameter by depending on Tyler series of two variables to propose a model mathematically.
