Ratio-type estimator of the population mean in stratified sampling based on the calibration approach

Pachori, Menakshi; Garg, Neha - In: Statistics in transition : an international journal of … 25 (2024) 2, pp. 39-55

An improved ratio-type calibrated estimator was developed using the logarithmic mean in the calibration constraint for the stratified random sampling scheme. The proposed estimator was extended in the case of stratified double sampling and compared with the estimators given by Tracy et al....

Estimation of finite population mean using two auxiliary variables under stratified random sampling

Yadav, Rohini; Tailor, Rajesh - In: Statistics in Transition New Series 21 (2020) 1, pp. 1-12

This paper addresses the problem of an alternative approach to estimating the population mean of the study variable with the help of the auxiliary variable under stratified random sampling. The properties of the suggested estimator have been studied under large sample approximation. It has been...

Estimating the population mean using a continuous sampling design dependent on an auxiliary variable

Wywiał, Janusz - In: Statistics in transition : an international journal of … 21 (2020) 5, pp. 1-16

Continuous distribution of variables under study and auxiliary variables are considered. The purpose of the paper is to estimate the mean of the variable under study using a sampling design which is dependent on the observation of a continuous auxiliary variable in the whole population....

Estimación de razón-remuestreo en muestreo estratificado

Padilla Terán, Alberto Manuel - 2016

In stratified sampling there are designs with one unit selected per stratum or when one is willing to make estimations on unplanned domains with one unit in some strata. In these cases the variance is generally estimated by the collapsed strata method, which requires identification of the strata...
