Abstract:
|
The geosciences have traditionally demanded sophisticated uses of statistics especially as it applies to data that is correlated over space and time and the need to estimate functional relationships among geophysical quantities. Some recent trends in the analysis of geophysical processes include much larger data sets that may be derived from several different sources and also the need to draw complicated inferences from spatial fields. This poster addresses some of these issues through a tutorial on the R packages fields and spam and by example with data analysis problems drawn from the geosciences.
