This unique book presents a learn-by-doing introduction to
geostatistics.
Geostatistics provides the essential numerical tools for
addressing research problems that are encountered in fields of
study such as geology, engineering, and the earth sciences.
Illustrating key methods through both theoretical and practical
exercises, Solved Problems in Geostatistics is a valuable
and well-organized collection of worked-out problems that allow the
reader to master the statistical techniques for modeling data in
the geological sciences.
The book's scope of coverage begins with the elements from
statistics and probability that form the foundation of most
geostatistical methodologies, such as declustering, debiasing
methods, and Monte Carlo simulation. Next, the authors delve into
three fundamental areas in conventional geostatistics: covariance
and variogram functions; kriging; and Gaussian simulation. Finally,
special topics are introduced through problems involving utility
theory, loss functions, and multiple-point geostatistics.
Each topic is treated in the same clearly organized format.
First, an objective presents the main concepts that will be
established in the section. Next, the background and assumptions
are outlined, supplying the comprehensive foundation that is
necessary to begin work on the problem. A solution plan
demonstrates the steps and considerations that have to be taken
when working with the exercise, and the solution allows the reader
to check their work. Finally, a remarks section highlights the
overarching principles and noteworthy aspects of the problem.
Additional exercises are available via a related Web site, which
also includes data related to the book problems and software
programs that facilitate their resolution. Enforcing a truly
hands-on approach to the topic, Solved Problems in
Geostatistics is an indispensable supplement for courses on
geostatistics and spatial statistics a the upper-undergraduate and
graduate levels.It also serves as an applied reference for
practicing professionals in the geosciences.
