Basics of areal data models
نویسنده
چکیده
Is there spatial pattern? Spatial pattern implies that observations from units closer to each other are more similar than those recorded in units farther away. Do we want to smooth the data? Perhaps to adjust for low population sizes (or sample sizes) in certain units? How much do we want to smooth? Inference for new areal units? Is prediction meaningful here? If we modify the areal units to new units (e.g. from zip codes to county values), what can we say about the new counts we expect for the latter given those for the former? This is the Modifiable Areal Unit Problem (MAUP) or Misalignment.

Order-free co-regionalized areal data models with application to multiple-disease mapping.
With the ready availability of spatial databases and geographical information system software, statisticians are increasingly encountering multivariate modelling settings featuring associations of more than one type: spatial associations between data locations and associations between the variables within the locations. Although flexible modelling of multivariate point-referenced data has recen...
متن کاملA Spatially Disaggregated Areal Interpolation Model Using Light Detection and RangingDerived Building Volumes
Dasymetric areal interpolation is the process by which data are transferred from a spatial unit system for which they are available (source units) to another system for which they are required (target units) with the aid of ancillary information (control units). We propose a spatially disaggregated areal interpolation model for population data using light detection and ranging (LiDAR)-derived b...

متن کاملGeneralized hierarchical multivariate CAR models for areal data.
In the fields of medicine and public health, a common application of areal data models is the study of geographical patterns of disease. When we have several measurements recorded at each spatial location (for example, information on p>/= 2 diseases from the same population groups or regions), we need to consider multivariate areal data models in order to handle the dependence among the multiva...

Heart is one of the most important members of the body, and heart disease is the major cause of death in the world and Iran. This is why the early/on time diagnosis is one of the significant basics for preventing and reducing deaths of this disease. So far, many studies have been done on heart disease with the aim of prediction, diagnosis, and treatment. However, most of them have been mostly f...
