Multiscale study of memory type simple ratio estimators in two stage sampling under exponentially weighted moving averages. [PDF]
Two-stage cluster sampling is often employed in survey sampling when complete population information is not available. In this setting, the Exponentially Weighted Moving Average (EWMA) statistic offers an efficient way to estimate the population mean by ...

Edgeworth expansions for two‐stage sampling with applications to stratified and cluster sampling [PDF]
AbstractA two‐term Edgeworth expansion for the standardized version of the sample total in a two‐stage sampling design is derived. In particular, for the commonly used stratified and cluster sampling schemes, formal two‐term asymptotic expansions are obtained for theStudentizedversions of the sample total.

Using Judgment Post Stratification in Two Stage Cluster Sampling
The judgment post stratification is a method of stratification of observation by using a key variable, such that stratification will be done after selecting the sample. In this paper, this method will use in two stage cluster sampling.

A Study of Sample Size for Two-Stage Cluster Sampling [PDF]
In a large scale survey, cluster sampling design in which a set of observation units called clusters are selected is often used to satisfy practical restrictions on time and cost. Especially, a two stage cluster sampling design is preferred when a strong intra-class correlation exists among observation units.

Local path planning for mobile robots based on improved OpenPlanner algorithm
The existing local path planning algorithms only achieve free movement of mobile robots in the scenario. But local path generation does not consider road constraints in the scenario, which is not applicable to some regularized structured roads.
