This Pan-American Advanced Study Institute consists of a winter
school with two workshops. The winter school, which will have
about 40 participants, covers a broad range of theoretical
and applied areas of spatial and spatio-temporal statistics, with
emphasis on climate, air pollution, and ecology. In parallel with
the winter school there will be two advanced workshops. The winter
school students are expected to also participate in the workshops.
One workshop will be dealing with nonstationary covariance
structures, and is aiming at a comparison of the various
approaches available in the literature. The other workshop covers
methods for multivariate spatial statistics. It will be possible
to participate only in the workshops, but such participation is by
invitation only. .
The schedule will leave the afternoons open for outdoor
activities, as winter in this part of Brazil generally is quite
pleasant.
Here are the results of a questionnaire before the conference started about the background of the participants.

W 6/18 - Sa 6/21
In most papers in the nonstationary covariance model literature,
comparisons are only made to stationary (or even isotropic)
models, not to other nonstationary approaches. There is a need for
an organized comparison of these models, and an assessment of what
models work in what circumstances. Furthermore, few of these
models have easily accessible software available, whence a
comprehensive software library is needed. The purpose of the
workshop is to compare the different methods, develop a library of
software, and produce a white paper with recommendations as to
what methods are most useful in what situations. P`articipants in
this workshop will have prepared in advance by analyzing a few
given data sets using their particular approach. In addition, the
method(s) of comparison of the approaches will have been
predetermined in discussion between the participants. The workshop
will last four days. The first two days will be presentations of
results. The third day will be devoted to producing an outline of
a paper detailing the comparison of the methods, while the final
day will be spent discussing how to set up the software library.
M 6/23 - Th 6/26
The intent of this workshop is to make participants aware of
different approaches to multivariate spatial models, how to
analyze multivariate spatial data, and what software is available
or needs to be developed. The goal of the workshop is to produce a
white paper on multivariate spatial statistics. Like the other
workshop, it will last four days. This will be a more traditional
type of workshop, with lectures and discussion groups.
