Dual Transformation of Auxiliary Variables by Using Outliers in Stratified Random Sampling
MathematicsTo estimate the finite population variance of the study variable, this paper proposes an improved class of efficient estimators using different transformations. When both the minimum and maximum values of the auxiliary variable are known and the ranks of

Improved Randomized Response in Optional Scrambling Models
Journal of Statistical Theory and Applications (JSTA), 2019 In the present study, we discuss the issue of increasing the respondents cooperation in sensitive surveys. When the question is highly sensitive then the cooperation from the respondents is decreased.
