mapping of stomach cancer rate in iran using area-to-area poisson kriging

Area-to-Area Poisson Kriging and Spatial Bayesian Analysis in Mapping of Gastric Cancer Incidence in Iran

Background: In many countries gastric cancer has the highest incidence among the gastrointestinal cancers and is the second most common cancer in Iran. The aim of this study was to identify and map high risk gastric cancer regions at the county-level in Iran. Methods: In this study we analyzed gastric cancer data for Iran in the years 2003-2010. Areato- area Poisson kriging and Besag, York and ...

Evaluation and mapping of soil salienty hazard in ramhormorz area (khozestan)using disjunctive kriging

تنظیم نقشه‌ جغرافیایی میزان بروز سرطان روده بزرگ در ایران طی سال‌های 1386-1382 با استفاده از روش کریگیدن پواسنی منطقه به منطقه

  Background : Large intestine cancer is ranked second among gastrointestinal cancers and is the fourth common cancer in Iran. The aim of this study is to map the county-level of large intestine cancer incidence rate in Iran using Area-to-Area Poisson Kriging method and also to identify the high-risk areas.   Methods : This study was application/ecology. The methodology was illustrated using la...

Application of Poisson kriging to the mapping of cholera and dysentery incidence in an endemic area of Bangladesh

BACKGROUND Disease maps can serve to display incidence rates geographically, to inform on public health provision about the success or failure of interventions, and to make hypothesis or to provide evidences concerning disease etiology. Poisson kriging was recently introduced to filter the noise attached to rates recorded over sparsely populated administrative units. Its benefit over simple pop...

Geostatistical analysis of disease data: accounting for spatial support and population density in the isopleth mapping of cancer mortality risk using area-to-point Poisson kriging

BACKGROUND Geostatistical techniques that account for spatially varying population sizes and spatial patterns in the filtering of choropleth maps of cancer mortality were recently developed. Their implementation was facilitated by the initial assumption that all geographical units are the same size and shape, which allowed the use of geographic centroids in semivariogram estimation and kriging....

Scaling Flux Tower Observations of Sensible Heat Flux Using Weighted Area-to-Area Regression Kriging

Sensible heat flux (H) plays an important role in characterizations of land surface water and heat balance. There are various types of H measurement methods that depend on observation scale, from local-area-scale eddy covariance (EC) to regional-scale large aperture scintillometer (LAS) and remote sensing (RS) products. However, methods of converting one H scale to another to validate RS produc...
