Improved Exponential Ratio – Product Type Estimator for finite Population Mean

  title={Improved Exponential Ratio – Product Type Estimator for finite Population Mean},
  author={Ran Vijay Singh and Ahmed Audu},
In this paper, an exponential ratio-product type estimator has been proposed for population under simple random sampling scheme. Expression for the bias and MSE of the proposed estimator have been derived up to first order approximation. The optimum MSE of the proposed estimator has been obtained. The efficiency of the proposed estimator has been compared theoretically and empirically with existing estimators. The empirical comparison shows that the proposed estimator is more efficient than… CONTINUE READING
