*2.6. Parameter Estimation*

After the reorganization of suitable model, the assessment of model parameters is attained with the help of the procedure and methods proposed by Box and Jenkins, the evaluation of model values for A.R and M.A parts were made possible. To ascertain the statistical significance of A.R and M.A parameters, they were tested whether they are important or not. The related parameters such as standard error of estimates and their linked *t*-values are also determined [48].
