Online and in-person classes:
Online courses on demand, on your schedule, for scientists in any time zone. Each course below will be offered through our Online Training Center.
Within the last year we have provided in-person, direct training to 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 the list of courses below can be taught at your location. These courses will be available online soon on our online training center

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.
Course Outline

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.
Course Outline

6. Statistical Methods for Contaminated Sites
Statistics for soils and groundwater. Meeting standards? Improving after remediation?
EPCs, UCLs, comparing to standards, and trend tests.
