Don't spin the pen: two alternative methods for second-stage sampling in urban cluster surveys

open access: yesEmerging Themes in Epidemiology, 2007
In two-stage cluster surveys, the traditional method used in second-stage sampling (in which the first household in a cluster is selected) is time-consuming and may result in biased estimates of the indicator of interest. Firstly, a random direction from

GENERALISED MODEL BASED CONFIDENCE INTERVALS IN TWO STAGE CLUSTER SAMPLING

open access: yesPakistan Journal of Statistics and Operation Research, 2010
Chambers and Dorfman (2002) constructed bootstrap confidence intervals in model based estimation for finite population totals assuming that auxiliary values are available throughout a target population and that the auxiliary values are independent. They also assumed that the cluster sizes are known throughout the target population. We now extend to two

Two-stage cluster sampling with unequal probability sampling in the first stage and ranked set sampling in the second stage

open access: yes, 2022
In this research work we introduce a new sampling design, namely a two-stage cluster sampling, where probability proportional to size with replacement is used in the first stage unit and ranked set sampling in the second in order to address the issue of ...

Interactive Linear Models in the Context of Two-Stage Sampling [PDF]

open access: yesJournal of Statistical Theory and Applications (JSTA), 2017
We study an interactive linear model that incorporates investigator and/or supervisor interventions in the context of a two-stage sampling design. We obtain an unbiased estimator of the finite population total and derive an unbiased estimator of its ...

Precision of Design Effect in Cluster Sampling [PDF]

open access: yesThe Egyptian Statistical Journal, 1993
A simulation study is performed to examine the precision of design effect in single-stage and two-stage cluster sampling without stratification and equal cluster sizes. Interest is focused on the effect on precision of such factors as sample size, number

Adaptive two-stage inverse sampling design to estimate density, abundance, and occupancy of rare and clustered populations.

open access: yesPLoS ONE, 2021
Sampling rare and clustered populations is challenging because of the effort required to find rare units. Heuristically, a practitioner would prefer to discontinue sampling in areas where rare units of interest are apparently extremely sparse or absent ...

Effects of Cluster Sizes on Variance Components in Two-Stage Sampling [PDF]

open access: yesJournal of Official Statistics, 2015
Abstract Determining sample sizes in multistage samples requires variance components for each stage of selection. The relative sizes of the variance components in a cluster sample are dramatically affected by how much the clusters vary in size, by the type of sample design, and by the form of estimator used.
