We propose a novel family of estimators for the population mean under non-response and obtain MSE equation suggested estimator each situation in theory. These theoretical conditions are applied to three popular data sets literature we see that more efficient than traditional estimators, such as ratio, regression Case 1; whereas, 2, also Unal-Kadilar exponential same sets.

Gupta and Shabbir (2008) have suggested an alternative form of ratio-type estimator for estimating the population mean. In this paper, we introduced new estimators by mixing two, stratified and cluster sampling method. Then we improved these estimators by using auxiliary variables and introducing new estimators. For sampling in infinite populations with a high geographic dispersion, the populat...

Installation of subsurface tile lines in poorly drained soils is a beneficial management practice that enhances crop productivity. In some instances, however, they can contribute to offsite losses of agricultural chemicals and sediment in drain flow. Movement of these materials through soil macropores (earthworm burrows and cracks) has been shown to contribute to this phenomenon. In order to de...
