Optimum estimator in simple random sampling using two auxiliary attributes with application in agriculture, fisheries and education sectors

Improved Mean Estimators for Population utilizing Dual Supplementary Characteristics under Simple Random Sampling

“…Ahmad et al [3] and Yunusa [4] developed a class of general type estimators for the parameters of a population using the information of auxiliary attributes. Saini et al [15] suggested optimum estimators under dual supplementary attributes with application in education, fisheries and agriculture areas. Wynn [22] proposed ratio mean estimator for population employing the characters of auxiliary variable in population proportion form.…”

A simulation study: An enhanced generalized class of estimators for estimation of population proportion using twofold auxiliary attribute

“…In such circumstances, estimators for population constraints can be created expending preceding knowledge of the auxiliary characteristics and the relationship amongst the study attribute and the auxiliary attribute. Several important studies, such as [ [1] , [2] , [3] , [4] , [5] , [6] , [7] , [8] , [9] , [10] , [11] , [12] , [13] , [14] , [15] , 16 , 17 , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] ] have recommended various estimators for the estimation of the exhausting auxiliary attribute of the determinate population proportion.…”
