Untangling Multivariate Relationships is our 2-day course covering the
multivariate methods of primary interest to environmental science,
focusing on seeing, testing, and modeling multivariate relationships.
Relationships between chemical and biological measures are used as
examples. Newer, nonparametric methods for establishing links between
variables supplant traditional methods dependent on multivariate
normality. UMR will be held Aug 24-25, 2009 at the Hilton Garden Inn
Downtown in Austin TX. Register online at our Upcoming Classes page:

Nondetects And Data Analysis, the course that illustrates methods for
correctly handling data with nondetects, will be held August 26-27
(just following the UMR course) at the Hilton Garden Inn Downtown in
Austin, TX. Register for both and save on travel dollars! Online
registration is available at

New topics include how to sum a series of components to get a total
when some components are nondetects. Stop substituting one-half the
detection limit, and make sense of data with nondetects.

Applied Environmental Statistics, our flagship 4.5 day overview of
statistical methods for environmental sciences, will be held in
Tacoma, Washington at the University of Washington-Tacoma on September
21-25. Topics include how hypothesis tests work, how to build
regression models, load estimation and trend analysis. New topics
include how to perform permutation tests and bootstrapping, both used
to avoid traditional assumptions of a normal distribution that are
questionable with environmental data.
** Also included, a free (optional) half-day introduction to using R
statistical software, for enrolled students only.
