Online versions of our in-person courses (below) will be available in the coming months.

#### In-Person Courses:

We have provided in-person, direct training to companies and organizations, including Federal, State, and River Basin agencies. Email us to find out what in-house, no-travel training would cost your company or agency. Any of our courses below can be taught at your location. Most will also be available soon through our Online Training Center, above.

###### 1. Applied Environmental Statistics
. . . .Statistics, down to Earth.
A 1-week survey of environmental statistics, from confidence, prediction and tolerance intervals to regression models and trend tests in many varieties. Parametric, nonparametric and permutation tests.
Course Outline

###### 2. Permutation Tests and Bootstrapping

Never worry about a normal distribution again! Learn how to compute bootstrap confidence intervals and regression. Perform the permutation equivalent of t-tests and ANOVA, without assuming and testing for normality. More power at no additional cost for testing the skewed data common to environmental studies.

###### 3. Untangling Multivariate Relationships

Discern and describe patterns and trends in multiple chemical and biological measures. Does the pattern of 35 chemicals jointly change over time? Which chemicals are most correlated with the shift in species composition? Which sites cluster together due to similarity in their patterns of species occurrence? How can I plot data in 35 dimensions? How can I perform a trend analysis over time or location in the pattern of 100+ organisms?
Course Outline

###### 4. Nondetects And Data Analysis

Statistical methods for data with nondetects.
How to compute means, UCL95s, hypothesis tests and regression and trend equations, all without substituting one-half the DL for nondetects.
Course Outline

###### 5. Time Series Methods for Frequently-Collected Data

Methods for frequently collected ("real-time") data, such as data collected at 1, 5, 15 minute intervals. These data often violate the independence assumption of standard statistical procedures -- without these methods, p-values for regression, and hypothesis tests will be incorrect.

###### 6. Practical Statistics for Site Investigations

Statistics for soils and groundwater. Meeting standards? Improving after remediation?
EPCs, UCLs, comparing to standards, and trend tests.
