Stratified Sampling: Some Associated Problems

Calcutta Statistical Association, Bulletin, 2023
Stratified sampling has been commonly used in many large-scale surveys. The two inter-related problems of determining strata boundaries where strata have to be developed using some variable(s) whose values can be accessed while designing the survey and ...

Global-Local Priors for Spatial Small Area Estimation

Calcutta Statistical Association, Bulletin, 2023
Small area estimation is gaining increasing popularity among survey statisticians. Since the direct estimates of small areas usually have large standard errors, model-based approaches are often adopted to borrow strength across areas.

Efficient Estimation of a Scale Parameter of Bivariate Lomax Distribution by Ranked Set Sampling

, 2021
Ranked set sampling (RSS) is an efficient technique for estimating parameters and is applicable whenever ranking on a set of sampling units can be done easily by a judgment method or based on an auxiliary variable.

Robust Difference and Ratio Type Estimators in Presence of Correlated Measurement Errors Under Ranked Set Sampling

Calcutta Statistical Association, Bulletin
In survey sampling, the problem of correlated measurement errors (CMEs) was initially addressed using conventional estimators under simple random sampling (SRS) and ranked set sampling (RSS).

Optimal Estimation of Population Mean Using Two Auxiliary Variables in the Presence of Non-response by Simulation Approach

Calcutta Statistical Association, Bulletin
In this article, we have proposed a difference-cum-exponential type estimator for estimating population mean by using information on two auxiliary variables under non-response, in which the expressions of bias and mean square error of the proposed ...
