The ongoing Small Area Income and Poverty Estimates (SAIPE) project at the Census Bureau estimates numbers of poor school-age children by state, county, and ultimately school district, based upon Current Population Survey (CPS) and IRS data along with information from the latest decennial census. The current SAIPE county-level methodology relies on a Fay-Herriot (1979) model fitted to log-count...
the use of manometry, i.e. the recording of pressures within hollow viscera, after being successfully applied to the study of esophageal and anorectal motor dysfunctions, has also been used to investigate physiological and pathological conditions of the small bowel. by means of this technique, it has been possible to understand better the normal motor functions of the small intestine, and their...
The Panoramic Survey Telescope and Rapid Response System 1 (Pan-STARRS1) survey is acquiring multi-epoch imaging in five bands (gP1, rP1, iP1, zP1, yP1) over the entire sky north of declination −30◦ (the 3π survey). In 2011 July a test area of about 70 deg2 was observed to the expected final depth of the main survey. In this, the first of a series of papers targeting the galaxy count and cluste...
Local statistical offices often dispose of very rich databases of spatially referenced socio– economic data. The high degree of spatial detail of such information is often not too useful for practical purposes in that firms or local authorities are interested in information aggregated at higher levels. The standard practice usually consists in aggregating the data at some prespecified geographi...
Abstract. National statistical offices are often required to provide statistical information about characteristics of the population, such as mean income or unemployment rate, at several administrative or small area levels. Having good area level estimates is important because policies will often be based on this type of information. In this paper we describe how Bayesian hierarchical models ca...
In this paper a geographical weighted pseudo empirical best linear unbiased predictor (GWEBLUP) for small area averages is proposed, and two approaches for estimating its mean squared error (MSE), a conditional approach and an unconditional one, are developed. The popular empirical best linear unbiased predictor (EBLUP) under the linear mixed model and its associated MSE estimator are obtained ...
Longitudinal surveys are very common in sampling over interval of times to estimate the aggregate level of population means at given point of time. In the present paper, the estimation methods have been developed for small area in longitudinal surveys using small area estimation (SAE) techniques. Direct, synthetic and composite estimators have been proposed to estimate the population mean of sm...
It has been claimed that unemployment affects the health and thus the mortality of the unemployed, their families, and other members of their communities. This paper examines the relation between mortality and the unemployment experiences of small areas which vary in the extent to which their unemployment levels have changed in recent years. Quarterly numbers of unemployed, classified by age, s...
There are many situations in which it is desirable to derive reliable estimators for small geographical areas or small subpopulations, from existing survey data. The basic random e ects model and corresponding small area predictors for small area estimation is introduced. There are also many situations in which it is necessary to have the total of the small area predictors equal to the total of...
