Performance of Small Cluster Surveys and the Clustered LQAS Design to estimate Local-level Vaccination Coverage in Mali [PDF]
, 2012 Background Estimation of vaccination coverage at the local level is essential to identify communities that may require additional support. Cluster surveys can be used in resource-poor settings, when population figures are inaccurate.

Nonignorable item nonresponse in panel data
Statistical Theory and Related Fields, 2022 To estimate unknown population parameters based on panel data having nonignorable item nonresponse, we propose an innovative data grouping approach according to the number of observed components in the multivariate outcome $ \boldsymbol {y} $ when the ...

The dwarf low surface brightness population in different environments of the Local Universe [PDF]
, 2007 The nature of the dwarf galaxy population as a function of location in the cluster and within different environments is investigated. We have previously described the results of a search for low surface brightness objects in data drawn from an East-West ...

Spatial Random Sampling: A Structure-Preserving Data Sketching Tool
, 2017 Random column sampling is not guaranteed to yield data sketches that preserve the underlying structures of the data and may not sample sufficiently from less-populated data clusters.

The star cluster - field star connection in nearby spiral galaxies. II. Field star and cluster formation histories and their relation [PDF]
, 2011 Recent studies have started to cast doubt on the assumption that most stars are formed in clusters. Observational studies of field stars and star cluster systems in nearby galaxies can lead to better constraints on the fraction of stars forming in ...

Developing a community-based breast cancer risk prediction tool for resource-poor settings
Journal of Education and Health Promotion, 2019 BACKGROUND: With an estimation of every two women newly diagnosed with breast cancer, one dies. It is accounted that 1 in 28 women is likely to develop breast cancer during her lifetime.

The Network Nullspace Property for Compressed Sensing of Big Data over Networks
, 2018 We present a novel condition, which we term the net- work nullspace property, which ensures accurate recovery of graph signals representing massive network-structured datasets from few signal values.
