                In  this  paper,  we  propose  the  new  multiple  ratio  estimator  and  the
            generalized  ratio-type  estimator  using  the  Taylor  series  approximation.  In
            particular,  the  generalized  ratio-type  estimator  has  the  advantages  of  the
            regression estimator which is accuracy, robustness. This estimator also has the
            advantages of the ratio estimator which is convenience of calculation, ease of
            use. Also these estimators can be used without estimation of ,  = 1,⋯ , .
