Calibration Approach Ratio Estimators of Population Median in Stratified Random Sampling Design

C. S. Agbebia & E. I. Enang · Asian Journal of Probability and Statistics · 2023

Median as a measure of location gives a more robust estimate than the mean when dealing with heavy tailed or skewed distributions. It can also be used in cases of qualitative variables and open end intervals. Calibration, an approach that adjusts the original design weight by inc...

Comparing Calibration Product Type Estimators of Population Mean In Stratified Sampling under Two Constraints Using Different Distance Measures

D. N. Ojua, J. A. Abuchu, E. O. Ojua & E. I. Enang · Journal of Advances in Mathematics and Computer Science · 2021

Calibration approach adjusts the original design weights by incorporating an auxiliary variable into it, to make the estimator be in the form of a regression estimator. This method was employed to propose calibration product type estimators using three distance measures namely; c...
