[PDF] Top 20 Improved Exponential Type Estimators for Finite Population Mean in Stratified Random Sampling

... MSE values of the k 1 , k 2 , y N and y M estimators have been obtained. These values are given in Table 2. When we examine Table 2, we observe that the proposed y M 4 estimator has the smallest. From Table 2 we ... See full document
