Cluster Analysis: Algorithms, Hazards and Small Area Relative Survival
… portfolio, analysis of relative survival at small area level has been made possible using a new level of geographical resolution that has recently been released in the United Kingdom. This study shows the benefits of using this new level of geography for small area studies of cancer survival …

Bayesian spatial models for adjusting nonresponse in small area estimation
… sometimes a sample is drawn from a large area although the estimate of interest is at a smaller sub-domain level. The sample sizes may be sufficient for inference at the large area, but too small to obtain accurate estimates at sub-areas. Analysis with multiple mailings and the small area …

Fay-Herriot Small Area Estimation in the Survey of Business Owners
This paper will study the use of the Fay-Herriot small area estimation model on the Survey of Business Owners and Self-Employed Persons (SBO) 2002 data. Small area estimation continues to be an important topic as the demand for reliable small area statistics continues to grow. Because direct …

HIERARCHICAL BAYES ESTIMATION AND EMPIRICAL BEST PREDICTION OF SMALL-AREA PROPORTIONS
… of units with a given characteristic for small areas using small area estimation (SAE) techniques is a common problem in survey research. The direct survey estimates, usually based on area-specific sample data, are very imprecise or even unavailable due to the small or zero sample sizes in …

Visualizing graphs with distinguishable edges and ordered binary trees in small area
… the known bounds on two aesthetic requirements (area and aspect ratio) for planar straight-line order-preserving grid drawings of binary trees is presented in a novel algorithm using a separations approach. The new bounds are optimal in area and aspect ratio, where the optimum values are linear …

Topics in small area estimation with applications to the National Resources Inventory
<p>A practical application of small area estimation in the National Resources Inventory, a large survey of the non-federal land area in the United States, is described. Several estimation issues raised by this application are discussed as motivation for theoretical investigation of some aspects of …

An investigation of social capital in Britain using small area estimation analysis
… of social capital and estimates them at small area level for England and Wales in 2011. The first step is the identification of three factors measuring membership, citizenship and politics and neighbourliness dimensions using survey data and a Confirmatory Factor Analysis. The second step …

A bayesian hierarchical modelling of small area variation in youth unemployment in Namibia
… (NLFS) does not provide such statistics at small area e.g., at constituency level. The census data could be used to provide estimates of youth unemployment at constituency level; however, the data is only obtained every 10 years which in most cases the time frame is too long given the …

Residential differentiation in post-soviet Lithuania (on the basis of small area Census data) /
The aim of dissertation is to start small area data (250-500 of inhabitants) based residential differentiation research in Lithuania. Population mobility during 1990s was low and year 2001 data represents a whole period quiet well. Principal component and cluster analysis methods were used and …

Improving Precision in Forest Inventory through Small Area Estimation for Loblolly Pine Plantations in Coastal Georgia
The use of small area estimation (SAE) in forest inventory has shown promise for improving the precision of estimates needed for informed decision-making when sample data are sparse. We evaluated the potential of unit-level SAE for increasing the precision of stand-level estimates of basal area, …

An evaluation of small-area statistical methods for detecting excess risk: with applications in breast and colon cancer mortality in Scotland 1986-1995
The need to report data at small-area level is constantly increasingly. In a society which is both health-conscious and environmentally aware, statistics at small-area level have a high degree of political significance. This type of data is required to plan and implement regional policies and …

Extending Space-Time Putative Hazard Models to Detect Latent Risk Features
<p>In recent years small area risk assessment modeling and data analysis around putative hazard sources has become a fundamental part of public health and environmental sciences. This dissertation work examines a novel development of three different space-time Bayesian hierarchical modeling …

Poverty mapping : what can we really learn?
… poverty mapping. I explain the difficulties of small area estimation arising from data sparseness and argue that any attempt to overcome this fundamental problem has to take the form of a conditional homogeneity assumption.

Granulite-facies metamorphism, fluid buffering and partial melting in the Buffels River area of the Namaqualand metamorphic complex, South Africa
The Buffels River area of central Namaqualand comprises a sequence of Proterozoic volcano-sedimentary gneisses intruded by granitoid orthogneisses. This study concentrates on the mechanisms of granrilite-facies metamorphism in a small area of isofacial rocks. Particular emphasis is placed on the …

The Spatial Distribution of Welfare in Ireland
