Bayesian Analysis of Finite Populations under Simple Random Sampling [PDF]
Entropy, 2021 Statistical methods to produce inferences based on samples from finite populations have been available for at least 70 years. Topics such as Survey Sampling and Sampling Theory have become part of the mainstream of the statistical methodology.

Simple-Random-Sampling-Based Multiclass Text Classification Algorithm [PDF]
The Scientific World Journal, 2014 Multiclass text classification (MTC) is a challenging issue and the corresponding MTC algorithms can be used in many applications. The space-time overhead of the algorithms must be concerned about the era of big data.

New adjusted missing value imputation in multiple regression with simple random sampling and rank set sampling methods. [PDF]
PLoS ONEThis research compared the efficiency of several adjusted missing value imputation methods in multiple regression analysis. The four imputation methods were the following: regression-ratio quartile1,3 (R-RQ1,3) imputation of Al-Omari, Jemain and Ibrahim;
