Abstract |
|
|
| In this manuscript, we have proposed two improved exponential ratio estimators using auxiliary information for estimating the unknown population mean in Adaptive Cluster Sampling (ACS) and have found the optimum value of a (the base of the exponent) using a numerical study. The Mean Squared Error for the two estimators has been derived up to first order of approximations and studied along with the nature of their percentage relative efficiencies for each and every positive real value of a except for 1.
