Estimation of Generalized Gompertz Distribution Parameters under Ranked-Set Sampling

Journal of Probability and Statistics, 2020
This paper studies estimation of the parameters of the generalized Gompertz distribution based on ranked-set sample (RSS). Maximum likelihood (ML) and Bayesian approaches are considered.

Generalized Power Transformation Estimators in Stratified Ranked Set Sampling using Auxiliary Information

International Journal of Bio-Resource and Stress Management, 2023
Auxiliary variable is commonly used in survey sampling to improve the precision of estimates. Whenever there is auxiliary information available, the researchers want to utilize it in the method of estimation to obtain the most efficient estimator ...

Bayesian Estimation of Log-Normal Distribution Under Ranked Set Sampling With Missing Data

IEEE Access, 2021
In this paper, joint Bayesian estimation of two parameters of a log-normal distribution is obtained based on simple random sampling (SRS) and ranked set sampling (RSS) with complete and missing data.

Half Logistic Inverted Nadarajah–Haghighi Distribution under Ranked Set Sampling with Applications

Mathematics, 2023
In this paper, we present the half logistic inverted Nadarajah–Haghigh (HL-INH) distribution, a novel extension of the inverted Nadarajah–Haghigh (INH) distribution. The probability density function (PDF) for the HL-INH distribution might have a unimodal,

Regression Estimators in Ranked Set, Median Ranked Set and Neoteric Ranked Set Sampling

Pakistan Journal of Statistics and Operation Research, 2018
This paper proposes new regression estimators in median ranked set and neoteric ranked set sampling using one and two auxiliary variables. The proposed estimators have large gain in presicion compared to the classical ranked set sampling (RSS) design. A simulation study is designed to see the performance of suggested estimators. A real data set example

Optimal Imputation Methods under Stratified Ranked Set Sampling

Revstat Statistical Journal
It is long familiar that the stratified ranked set sampling (SRSS) is more efficient than ranked set sampling (RSS) and stratified random sampling (StRS). The existence of missing values alter the final inference of any study.

On Some Improved Class of Estimators by Using Stratified Ranked Set Sampling

Mathematics, 2022
In this manuscript, we propose the combined and separate difference and ratio type estimators of population mean using stratified ranked set sampling. Additionally, several well-known estimators are identified as the sub-class of the suggested estimators.

Improved Estimation from Ranked Set Sampling

Hacettepe Journal of Mathematics and Statistics, 2014
Ranked set sampling is used when the measurement or quantification of units of the variable under study is difficult but the ranking of units of sets of small sizes can be done easily by an inexpensive method. Dell and Clutter (1972) showed that the sample mean based on ranked set sample is more efficient than the sample mean based on simple random ...

Ranked Set Sampling Based Regression Estimators in Two-Stage Sampling Design

Journal of Statistical Theory and Applications (JSTA)
This paper examines the use of ranked set sampling in the second stage of the two-stage sampling design to improve the regression estimator. The mean square errors of the suggested estimators are computed, and both theoretical and simulation results ...
