The Nature of Simple Random Sampling [PDF]

open access: yesAnnals of Statistics, 1984
As an estimator of the population mean, the sample mean based only on the distinct units possesses a remarkable invariance property. Under three forms of simple random sampling, viz. simple random sampling without replacement (SRSWOR), simple random sampling with replacement (SRSWR), and fixed cost simple random sampling (SRSFC), it is admissible and ...

Bayesian Analysis of Finite Populations under Simple Random Sampling [PDF]

open access: yesEntropy, 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]

open access: yesThe 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.

Evaluating the performance of memory type logarithmic estimators using simple random sampling [PDF]

open access: yesPLoS ONE, 2022
In survey research, various types of estimators have been suggested that consider only the current sample information to compute the unknown population parameters.

Parameter Estimation of the Exponentiated Pareto Distribution Using Ranked Set Sampling and Simple Random Sampling

open access: yesAxioms, 2022
In this paper, we have considered that ranked set sampling is able to estimate the parameters of exponentiated Pareto distribution. The method with which the maximum likelihood estimators for the parameters of exponentiated Pareto distribution is studied

Estimation of population median using bivariate auxiliary information in simple random sampling [PDF]

open access: yesHeliyon
To estimate the unknown population median, several researchers have developed efficient estimators but these estimators are unable to provide efficient results in the existence of outliers.

On conditional simple random sample [PDF]

open access: yesStatistics in Transition new series, 2014
Estimation of the population average in a finite and fixed population on the basis of the conditional simple random sampling design dependent on order statistics of the auxiliary variable is studied. The sampling scheme implementing the sampling design is proposed. The inclusion probabilities are derived. The well known Horvitz-Thompson statistic under

New adjusted missing value imputation in multiple regression with simple random sampling and rank set sampling methods. [PDF]

open access: yesPLoS ONE
This 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;

Improvement in variance estimation using transformed auxiliary variable under simple random sampling [PDF]

open access: yesScientific Reports
This paper offers a novel approach to formulate efficient ratio estimator of the population variance using a transformed auxiliary variable. The impact of transformation on auxiliary information has also been discussed.
