Partial stratified ranked set sampling scheme for estimation of population mean and median.
PLoS ONE, 2023 Ranked set sampling is an alternative to simple random sampling, which uses the least amount of money and time. The ranked set sampling (RSS) is modified to obtain a more efficient and cost-effective estimator of population parameters. This paper aims to

Ratio Type Estimator of Ratio of Two Population Means in Stratified Random Sampling [PDF]
, 2012 A ratio estimator is proposed for the ratio of two population means using auxiliary information in stratified random sampling. Bias and mean squared error expressions are obtained under large sample approximation, and the proposed estimator is compared ...

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 ...

Filtering Nonuniformly Sampled Grid-Based Signals [PDF]
, 2018 This paper presents an example application of digital alias-free signal processing, where a sequence of irregularly spaced, yet uniformly gridded, samples of a bandlimited discrete-time signal is filtered by using an oversampled finite impulse response ...

A quasi-random sampling approach to image retrieval [PDF]
, 2008 In this paper, we present a novel approach to contentsbased image retrieval. The method hinges in the use of quasi-random sampling to retrieve those images in a database which are related to a query image provided by the user.

Stratification in Business and Agriculture Surveys with R [PDF]
Revista Română de Statistică, 2016 Usually sample surveys on enterprises and farms adopt a one stage stratified sampling design. In practice the sampling frame is divided in non-overlapping strata and simple random sampling is carried out independently in each stratum.

Cat swarm optimization for the determination of strata boundaries [PDF]
Yugoslav Journal of Operations Research, 2023 A stratified random sampling method is preferred for selecting varied populations with outliers. As opposed to plain random sampling, stratified sampling increases statistical precision by reducing estimator variance.
