The Numerical Methods to Estimation the Missing Values of Data in Time Series.

Abstract

This Research discuss the estimation of presumptive missing Values of time Series which assume mean maximal temperature degree in AL-Musil for(2001) in numerical methods (Least Squares – Cubic Spline – divided differences – Lagrange interpolation). Then Comparison between these methods to find the best method for estimation the missing values in the mean maximal and minimal temperature degree in AL-Musil for (2003).
