Fairbanks Area - Chena Hot Springs Resort, Alaska, July 31- August 1
The following was 'adapted' from the June 1997 Chapter Newsletter:
The 1997 Annual Meeting will be held this year from July 31st
through August 2nd, at Chena Hotsprings Resort.
Our featured speaker will be Dr. Dale Zimmerman, University of
Iowa. Dr. Zimmerman will give two presentations: (1) Variance-Covariance
Structures for Longitudinal and Spatial Data; and (2) Analysis
of Spatial Point Patterns. Both talks are scheduled for the morning
sessions of the first two days of the meeting.
Dr. Zimmerman provided the following descriptions for his presentations:
VARIANCE-COVARIANCE STRUCTURES FOR LONGITUDINAL AND SPATIAL
DATA
A feature common to both longitudinal and spatial data is the
presence of correlation among observations. Properly accounting
for this correlation, rather than ignoring it or "randomizing
it away," generally results in a more efficient and penetrating
statistical analysis. This is particularly so if the correlation
has a discernible structure that can be modeled parsimoniously.
In this talk I review some commonly used variance-covariance structures
for longitudinal and spatial data and the underlying stochastic
models that give rise to them. Maximum likelihood estimation of
model parameters, assuming normality, is presented. Several aspects,
both conceptual and computational, of this modeling and estimation
paradigm are considered. Commonalities of, and differences between,
the implementation of this paradigm for longitudinal and spatial
data are emphasized. Worked examples, using SAS PROC MIXED, are
included.
ANALYSIS OF SPATIAL POINT PATTERNS
A spatial point pattern, for example a map of eagle nests, is
a set of points, usually in a two- or three-dimensional region,
for which some aspect of the locations is of interest. Statistically,
a spatial point pattern is typically regarded as a partial realization
of a spatial point process, i.e. a random mechanism for generating
points. In this presentation I review several useful spatial point
process models and discuss approaches to several inference problems,
including tests for complete spatial randomness, tests for isotropy,
estimation of intensity, and tests for independence in multi-species
patterns. Worked examples, using S+SpatialStats, will be presented.
