Course description
Environmental impact assessments want to know if trends over time differ between control and impact sites. Statistical methods for the analysis of trends over time use many of the same methods as the analysis of experimental data (e.g. ANOVA, regression) but must now deal with problems such as autocorrelation and process error.
Course content
- Review of statistical concepts on estimates, standard errors, confidence intervals, p-values, bias, precision, accuracy,
missing values, etc. - Detecting linear changes over time
Regression and non-parametric methods
Power and how many years to monitor
Dealing with seasonality and autocorrelation
Sampling vs process error
Pooling slopes (ANCOVA) - Detecting step changes over time
ANOVA and non-parametric methods
Power and how many years to monitor
Dealing with seasonality and autocorrelation
Sampling vs process error - BACI designs and variants
Simple Before and After Controlled Impact design (BACI) – Introduction to two factor ANOVA
BACI with multiple sites
BACI with multiple years/multiple sites before/after
Paired BACI with multiple years/multiple sites before/after
Regression BACI (analysis of covariance)
Power/sample size
