Exponential-type regression compromised imputation class of estimators

Regression-type Imputation Class of Estimators using Auxiliary Attributes

“…However, when the study variables are characterized by non-response, the aforementioned estimators are not applicable. Authors like Singh and Horn [10], Singh and Deo [11], Wang and Wang [12], Toutenburg et al [13], Kadilar and Cingi [14], Singh [15], Diana and Perri [16], Al-Omari et al [17], Singh et al [18], Gira (2015), Singh et al [19], Bhushan and Pandey [20], Prasad [21], Audu et al [22][23][24], have studied different schemes and estimators in the presence of non-response. Situations arise when the auxiliary characters are qualitative in nature e.g.…”

Difference-Cum-Ratio Estimators for Estimating Finite Population Coefficient of Variation in Simple Random Sampling

“…Several authors like Singh HP et al, [1], Sahai A et al [2], Srivastava Sk et al [3], Ahmed A et al [4], Audu A et al [5], Audu A et al [6], Muili JO et al [7] have worked extensively in that direction. Authors like Singh HP et al [8], Sisodia BVS et al [9], Khoshnevisan M et al [10], Singh RVK et al [11], Ahmed A et al [12] and Audu A et al [13] utilized coefficient of variation of auxiliary variable in the estimators formulation and obtanied highly efficient estimators. Nevertheless the investigators did not emphasized on the problem of estimation of coefficient of variation.…”

Logarithmic Ratio-Type Estimator of Population Coefficient of Variation

“…For estimating population parameters like population mean, population variance, standard deviation etc. of the study variable using information on auxiliary variable, a considerable amount of work has been already performed by several researchers like Sisodia and Dwivedi [1], Murthy [2], Yadav and Kadilar [3], Singh and Tailor [4], Bahl and Tuteja [5], Singh et al [6], Singh et al [7], Kadilar and Cingi [8], Singh and Solanki [9], Sahai and Ray [10], Srivastava and Jhajj [11], Ahmed et al [12], Audu and Adewara [13], Audu et al [14], Muili et al [15], Khoshnevisan et al [16], Singh and Audu [17], Ahmed et al [18] and Audu and Singh [19], Das and Tripathi [20], Das and Tripathi [21], Patel and Rina [22], Rajyaguru and Gupta [23], Rajyaguru and Gupta [24], Archana and Rao [25], Singh et al [26], Audu et al [27][28][29][30][31][32], Singh et al [33], Muili et al [34], Ishaq et al [35]. Nevertheless, the investigators did not much emphasize for the problem of estimation of coefficient of variation for a long time.…”
